00:00:03CandidateThe informant is the patient herself; she is reliable. Chief complaints: dyspnea on exertion for the past 4 years, increased over the past 3 months; palpitations for the past 3 months; pedal edema for the past 2 months. Since the past history is significant, I would like to describe it first.
00:00:19FacultyNo, tell me the symptoms again, please.
00:00:23CandidateShortness of breath for 4 years, more since 3 months; palpitations for 3 months; pedal edema for 2 months. The past history of the patient is significant, and I would like to describe it first. At 35 years of age, the patient was admitted with...
00:00:42FacultyYou are going back to the past history?
00:00:45CandidateYes, sir.
00:00:48FacultyYou don't have to go from past to present like that. You can start from the beginning, what she had, and continue till the present time. That also can be done.
00:00:52CandidateAt 35 years of age, the patient was admitted with dyspnea and underwent a balloon dilatation procedure [unclear]. She later underwent two more such procedures over a span of 6 years; the last procedure was in 2013. After this she was asymptomatic, but was advised to take an intramuscular injection every 21 days, which she took for 4 years. Later, due to local site pain, it was switched over to oral medication. She was followed up for 5 years after the procedure and was later lost to follow-up.
00:01:27For the past 4 years she has complained of dyspnea. Initially she was able to do all household activities but became dyspneic on exertion. For the past 3 months she has been dyspneic during household activities and on climbing one flight of stairs, progressing from NYHA class I to class III. The dyspnea increases on lying down and is associated with cough. She also complains of palpitations for the past 2 months, which occur during exertion and are not associated with giddiness, blurring of vision or loss of consciousness. The palpitations are regular in nature.
00:02:07She also complains of pedal edema, which decreased with medication. For the above complaints she visited an outside hospital 2 months ago, where she was evaluated, told that she would need surgery, and referred to this institute. There is no history of chest pain, loss of consciousness, abdominal distension, hemoptysis or any focal neurological deficit. There is no history of sore throat or joint pain in childhood.
00:02:36Obstetric history: P2 L1. She has a 22-year-old daughter; her 18-year-old son died 4 years ago in an accident. Both pregnancies were full-term normal vaginal deliveries, and the pregnancy and postpartum periods were uneventful. Family history is not significant. Summarising the case of a [unclear]-year-old...
00:02:58FacultyHold on, hold on. See, good, you started from the beginning, but before the balloon dilatation we want to know what symptoms she had at the time they opted for balloon dilatation, because that will give us an idea. You can even start with whether there was any rheumatic fever; you said there is no rheumatic fever. That is the way you can present in the exam, because in the exam you won't have time, especially if you are the fourth candidate presenting. So start with what happened before the balloon dilatation, then come to the balloon dilatation and whatever came after, because these are all related.
00:03:41I think it is not a separate history. I specifically asked how many years she had the disease process. It probably started as mitral stenosis and she underwent balloon valvotomy; from whatever you described there is no other possibility in this. So it is a continuum. As sir said, start from the initial symptom before the balloon and present from there. That will be better.
00:04:07CandidateShe had only dyspnea, sir.
00:04:07FacultyBut for how many years did she have dyspnea before the procedure?
00:04:11CandidateShe is not able to recall, sir, and she is not able to recall the exact year of the procedures either. She speaks Tamil and there was some language difficulty, sir.
00:04:19FacultyWere both done here?
00:04:19CandidateYes, previously done here only.
00:04:27FacultyThere was no PND history?
00:04:27CandidateNo, sir. Orthopnea is there, on lying down. No PND.
00:04:32FacultyWhat is the importance of having orthopnea? Which is the worse symptom?
00:04:37CandidateOrthopnea is worse. Immediately on becoming recumbent there is increased preload from the venous system, which cannot be accommodated by the heart. So orthopnea is more severe than PND.
00:04:53FacultyWith the palpitations you mentioned some associated history. What all did you say?
00:04:56CandidateI said there is no history of giddiness, blurring of vision or loss of consciousness.
00:05:04FacultyAny other history you will ask? Post-palpitation diuresis: in which condition will you get it? In supraventricular tachycardia?
00:05:13CandidateIn SVT the patient can have diuresis because of release of ANP from the atria. There can be diuresis after SVT, sir.
00:05:21FacultyOkay. Can you tell me the hemodynamic sequence? What is she currently having?
00:05:27CandidateShe has increased pulmonary capillary pressure...
00:05:33FacultyFor the last 4 years. The history is the problem.
00:05:33CandidateYes. She has predominantly increased LA pressure, and dyspnea because of increased LA pressure and pulmonary capillary pressure. Along with this she has palpitations, which are exertional. It looks like volume overload, so I am suspecting an additional regurgitant lesion which can cause this palpitation in MS. Even in MS, AF can be a cause of palpitation, but the palpitation she described is regular and on exertion. So I would like to keep a regurgitant lesion, aortic regurgitation, as one of my possibilities. My first differential would be MS with MR or AR, and the second would be pure MS with AF. For the palpitations, I asked her to tap them out; she was not able to, but she said they are regular.
00:06:25FacultySo which is more likely, MR or AR?
00:06:31CandidateMore likely MR, sir.
00:06:31FacultyIf after the BMV she was totally asymptomatic, why are you considering MR in this?
00:06:40CandidateIt could have progressed after BMV. She could have had grade 1 or grade 2 MR, which would have progressed over the years.
00:06:49FacultyAnd is that likely? Severe MS was opened up, with no MR at that point. More likely it can be aortic regurgitation.
00:06:52CandidateYes.
00:07:02FacultyWas there fatigue?
00:07:02CandidateShe describes dyspnea and fatigue together, sir. The pedal edema is because of RV failure, because of pulmonary hypertension.
00:07:16FacultyMS causing pulmonary hypertension, followed by pedal edema. Can it persist due to right-sided valve disease like TR?
00:07:22CandidateYes, sir, TR. If it is rheumatic, TS and TR can be there, which can cause pedal edema.
00:07:32FacultyWhen there is TS [unclear], dyspnea will not be there.
00:07:34CandidateYes, dyspnea will decrease.
00:07:41FacultyBut once TS sets in, right heart failure features will go up, but the output from the right side will decrease. Dyspnea will decrease, but fatigue will [unclear] with organic tricuspid disease. They purchase relief of dyspnea at the price of fatigue. That's what it is: breathlessness reduces, fatigue increases, right heart failure features go up.
00:08:15Okay, so with this history, what are the likely possibilities?
00:08:18CandidateLikely she has acquired valvular heart disease, rheumatic multivalvular disease. Initially she had RHD with MS and BMV was done. Now she is having mitral restenosis and AR.
00:08:34FacultyShe underwent BMV three times.
00:08:41CandidateSo I am saying it is mitral restenosis and AR, with PH and TR.
00:08:46FacultySo which one will you consider as the first possibility?
00:08:51CandidateThe first possibility is restenosis, sir: severe mitral disease with AR.
00:08:57FacultyBut you said MR was one of the first possibilities you thought of initially.
00:09:01CandidateI reconsidered when you said that post-BMV, in the acute phase, you may have MR, but it won't progress after that. In the multiple case series also, the MR did not progress over long-term follow-up.
00:09:16FacultySuppose the last BMV produced MR, and it was, say, moderate or mild. Can it progress?
00:09:26CandidateLess likely, sir.
00:09:29FacultyIt is unlikely, but if the patient [unclear: possibly 'is not on secondary prophylaxis'], the level of MR can go up, it can go on to the right heart, and as you say she can develop pedal edema. It can happen that way.
00:09:45What are the mechanisms of pulmonary hypertension in mitral stenosis?
00:09:51CandidateFirst, because of increased LA pressure: backward, passive pressure transmission. Second, reactive pulmonary vasoconstriction; over time there can be pulmonary vascular obliteration, and PVOD also can develop. Third, structural changes. These are the three reasons.
00:10:13FacultyWhen you do a BMV for severe MS with severe PH, among these mechanisms producing PH, what all will come down, and over what time period? What happens on table, after the procedure?
00:10:27CandidateThe LA pressure and pulmonary capillary pressure will decrease, sir. The LA-to-LV gradient also will decrease, the area will increase, and over time the PVR will eventually come down.
00:10:40FacultyYou said there are three components. The passive component will come down immediately, if it is a good BMV and there is no MR.
00:10:44CandidateYes, sir.
00:10:48FacultyThen what happens to the reactive component?
00:10:50CandidateThe reactive component also will come down over time.
00:10:52FacultySome will come down immediately, but it will take some time; people say it will come down further up to 6 months or one year. What happens to the structural damage that has already occurred? That will persist, or may actually progress. It will relatively persist and will not come down.
00:11:06What is the transpulmonary gradient?
00:11:12CandidateThe transpulmonary gradient is the difference between the mean pulmonary artery pressure and the left atrial pressure.
00:11:19FacultyHow much is normal?
00:11:19Unclear[Numbers unclear.] The mean transpulmonary gradient, not the diastolic gradient...
00:11:34FacultySo what happens in post-capillary, pre-capillary and combined PH? How do you know it is post-capillary PH?
00:11:39CandidateBy the pulmonary capillary wedge pressure and by measuring pulmonary vascular resistance, you can find out whether it is pre-capillary or post-capillary. In pre-capillary PH there will be an increase in the transpulmonary gradient and in the pulmonary vascular resistance; in pre-capillary the transpulmonary gradient will remain high, ma'am, and in post-capillary it will decrease.
00:12:07In post-capillary PH there is a rise in LA pressure and pulmonary capillary wedge pressure, so the transpulmonary gradient will be the same, normal. In pre-capillary the transpulmonary gradient will increase. In post-capillary the diastolic gradient increases, but the transpulmonary gradient remains almost the same.
00:12:34Unclear[unclear] Sir is not asking about after the procedure, but normally: how to differentiate pre-capillary from post-capillary PH?
00:12:42CandidateIn pre-capillary PH, the mean transpulmonary gradient will be increased.
00:12:47FacultyIn pre-capillary, correct. The transpulmonary gradient will be increased. Something else?
00:12:58What is 'second stenosis'?
00:12:58CandidateBecause of reactive pulmonary vasoconstriction there will be an increase in pulmonary hypertension.
00:13:06FacultyWhat happens? What pathology happens?
00:13:12CandidatePulmonary reactive constriction: pulmonary artery constriction.
00:13:19FacultyMain pulmonary artery, [unclear], or what? At which level?
00:13:27UnclearAt the level of the arterioles, the pre-arterioles.
00:13:35FacultyWhat is the hypothesis?
00:13:41CandidateWood's hypothesis.
00:13:41FacultyWhat is the [unclear] of Wood's hypothesis? It is one of the mechanisms described: the 'second stenosis'. What is second stenosis?
00:14:08CandidateExamination: a [unclear]-year-old female, oriented to time, place and person. Height 158 cm, weight 62 kg, BMI 24.8. Pulse 84 beats per minute, regular, normal volume, normal character; no radio-radial or radio-femoral delay; all peripheral pulses felt.
00:14:26FacultyWhat is the pulse rate?
00:14:26Candidate84, sir. Regular.
00:14:33Blood pressure: right upper limb 130/60 mmHg, left upper limb 132/64; lower limb systolic blood pressure 140. Saturation 99% in all four limbs. Afebrile. JVP is 2 cm above the sternal angle, with normal waveforms and normal respiratory variation.
00:14:56Faculty2 cm above the sternal angle?
00:14:56CandidateNo, sir, total 5 plus 2, 7 cm.
00:15:04FacultyYou saw the JVP in the sitting position or in which position?
00:15:08CandidateAt 45 degrees, sir. In the sitting position the JVP was not visible.
00:15:14FacultySo it is normal, not elevated. 2 is normal, up to 3. Revise the JVP. Tell the JVP again.
00:15:19CandidateYes, sir, JVP is 2 cm above the sternal angle.
00:15:25FacultyJVP elevated or not elevated?
00:15:25CandidateNot elevated, sir.
00:15:28FacultyOkay. In the sitting position it is not visible, so the JVP mean pressure is not elevated: in the sitting position you are not seeing it above the clavicle.
00:15:39How do you measure the JVP if the wave is above, near the angle of the mandible?
00:15:44CandidateIf it goes above the angle of the mandible in the sitting position, you can raise the hand. What is it called...
00:15:54FacultyWhose manoeuvre is it called? Okay, no need of the name.
00:15:54UnclearGaertner's.
00:16:00CandidateIdentify a basilic vein or some vein in the arm, lift the arm, and then measure the vertical distance.
00:16:07FacultyCan you make the patient stand, or sit with the legs dangling, if you are not seeing the upper level?
00:16:11CandidateYes.
00:16:14FacultyYou can do that. But this is enough: patient in the sitting position, not visible above the clavicle, so the JVP is normal. That's what it is. So what do you think is the mean venous pressure in this patient?
00:16:29Candidate7 cm of water. So it will be equal to around...
00:16:32FacultyWhy do you want water? How do you say 7 cm? You didn't see anything above the clavicle. Then how are you calculating?
00:16:39CandidateAt [unclear] degrees it was 2 cm from the sternal angle, so 2 plus 5 is 7, just adding the RA-to-sternal-angle distance.
00:16:48FacultyOh, at 45 degrees you used it. How did you measure RA to the sternal angle as 5 cm?
00:16:52CandidateAssuming.
00:16:54FacultyRA to sternal angle is 5 cm, which is not true in everyone, but assuming it to be fixed, from there it is 2 cm, so a total of 7 cm...
00:17:02Candidate...of water, which will be equal to 5 to 6.
00:17:05FacultyWhy do you want to bring water here? Where did you get water from?
00:17:09CandidateWater for blood, sir. Blood.
00:17:14FacultyThere is a conversion factor for that also. What I am saying is, in the exam, don't get caught on the JVP like this by quoting the sternal angle. Just say that in the sitting position I could not see the JVP, so the mean pressure is normal.
00:17:31CandidateIn that case, do the waveforms have to be seen or not?
00:17:34FacultyYes. You can say that at 45 degrees you saw the waveforms. The mean JVP is not elevated, which you have already mentioned, and then the waveforms. You can't say 'I have not seen the waveform in the sitting position.' You will have to put the patient down, make it appear in the neck and observe the waveform. You have to put the patient at an appropriate angle so that it becomes manifest in the neck.
00:17:58Also the abdominojugular reflux. How will you elicit it?
00:18:05CandidateWe should ask the patient to breathe normally...
00:18:05FacultyIn what position will you put the patient?
00:18:09CandidateSupine position at 45 degrees.
00:18:12FacultySupine position, correct?
00:18:12CandidateSupine, with the neck elevated at 45 degrees: lying down, neck at 45 degrees. Relax the abdomen; you can fold the legs to relax the rectus abdominis.
00:18:21FacultyIs the supine position correct or not? First, why do you want to fold the legs? What will happen?
00:18:27CandidateThe rectus abdominis will relax, so that when you press, they won't voluntarily guard.
00:18:30FacultyYou will increase the preload. No.
00:18:35Let me make it clear to everybody. Don't put the patient in the supine position while you are trying to do the abdominojugular test. Put the patient at an angle where the upper level is just seen. As you keep on decreasing the angle, at one particular point you will be able to see the upper level of the JVP, the mean pressure. Keep the patient at that particular point and then give the compression of the abdomen. There is a particular angle at which you have to keep the patient to make the upper level of the JVP appear.
00:19:04Where will you give the pressure?
00:19:08CandidateRight upper quadrant or centre; it can be given over the entire abdomen, sir. If the patient has a tender hypochondrium we avoid it; otherwise it can be given over the right hypochondrium or the centre of the abdomen.
00:19:20FacultyOur idea is to increase the abdominal pressure. You can give it anywhere; anywhere is fine. Okay, now how long will you give it, and what is the result?
00:19:28CandidateResponse: 30 seconds [unclear]. Any elevation, if it persists for less than 3 seconds, is normal.
00:19:33Faculty3 seconds?
00:19:38Candidate3 cycles.
00:19:38Faculty3 cycles of what?
00:19:42CandidateCardiac cycles.
00:19:42FacultyWhat is the length of each cardiac cycle?
00:19:45Candidate800 milliseconds, depending on the heart rate.
00:19:45FacultyNo, that's why: it depends on the compression you give, not on the cardiac cycle. Which book are you referring to? What's your reference for this? This question will always be asked in the examination. Speak from the books. Don't say 'my teacher taught'; he will not come to your rescue there. 'Told in our clinics' counts for nothing. You always have to quote from books. So which book is your reference?
00:20:16CandidateJonathan Abrams. [unclear] three cycles, he said.
00:20:26FacultyNow, what is the physiological basis of this abdominojugular reflux on compression?
00:20:28CandidateOn compression of the abdomen there is increased venous return to the right ventricle. A normal ventricle will be able to handle the increase in volume. If there is [unclear] in the ventricle or any impending RV failure, the ventricle won't be able to accommodate the extra volume, and this will manifest as a rise in the JVP.
00:20:46FacultyThat is the point. The extra volume coming to the RA will not be handled by the system, so the mean pressure will go up. That is the mechanism. Okay, go ahead.
00:20:59CandidateNo pallor, icterus, cyanosis, clubbing or lymphadenopathy. No peripheral signs of acute rheumatic fever. Pistol-shot sound over the femoral artery and Duroziez's murmur are present; these are peripheral signs of AR. The diastolic pressure was around 60.
00:21:13FacultyBut you said the pulse is normal, of normal character, and then you got a pistol-shot sound?
00:21:23CandidateWith the pulse, yes sir, normal character.
00:21:25FacultyYour volume is normal, but your BP is 130/60. The pulse pressure is 70; the pulse pressure is wide. And one more discrepancy: your lower limb blood pressure is only 140.
00:21:40Candidate140 approximately. Severe MS could mask the Hill sign. The discrepancy could be masked by the [unclear] stenosis, underestimating [unclear].
00:21:56FacultyWhen you have a combined lesion, it depends upon the severity. If the pulse pressure is more than 40 and the diastolic pressure is less than 60, then AR is not masked; AR is likely to be dominant. If the pulse pressure is less than 40 and the diastolic pressure is more than 60, it is likely that MS is masking it.
00:22:16Candidate[unclear] 64, sir. BP [unclear] 64, sir. I thought I was speaking into the mic.
00:22:29FacultySo that is 64 [unclear]. Okay, pulses, okay.
00:22:46Cardiovascular system: inspection and palpation. [unclear] You can't have pistol-shot sounds and Duroziez's murmur with [unclear] normal. They are among the sensitive signs. These are the only three signs of AR. What are the three signs?
00:23:06UnclearPeripheral signs: [unclear], and pistol-shot sound, or Traube's sign.
00:23:06FacultyThat's all it is. The others are all just for the sake of enumerating.
00:23:27What BP apparatus are you using?
00:23:33CandidateMercury sphygmomanometer.
00:23:38FacultyBut currently we don't have mercury manometers; now they are banned.
00:23:43UnclearIt was there here.
00:23:43FacultyNo, it is not available in most places. So muffling and so on, we are not able to make out. Okay, what is the mechanism of the usual Omron? How do they assess the blood pressure? What is the method called?
00:24:12CandidateOscillometric.
00:24:12FacultyHow do they derive the pressures?
00:24:16CandidateOnly the mean pressure can be derived, sir; the rest is calculated.
00:24:19FacultyThe mean is derived, and from that the systolic and diastolic are derived. Okay, so that is the problem. Okay.
00:24:28CandidateInspection and palpation: no visible pulsations over the precordium. The apex is localised to the 5th intercostal space in the midclavicular line; it is tapping type.
00:24:37FacultyIn the midclavicular line and tapping type? You are not feeling the apex at all?
00:24:49CandidateIt's best felt there. The apex is of normal character, sorry. Normal apex.
00:24:59FacultyNormal apex? No. What is the duration? What is it here? In your patient, is it a normal apical character, or tapping?
00:25:09CandidateNormal, sir: not hyperdynamic or heaving. It is normal. No cardiomegaly, no abnormal [unclear], with respect to both site and character of the apex.
00:25:26FacultyI think we need a little clarification here. What is a normal apical impulse and what is a tapping apical impulse? Are they both the same?
00:25:37UnclearYes. No.
00:25:40FacultyBoth are the same? Tapping and this one are both the same? No. Anyone? What is a normal apical impulse?
00:25:53UnclearThe lowermost, outermost, perpendicular thrust, confined to one intercostal space, medial to the midclavicular line.
00:25:58FacultySo these are the various components: it should be a perpendicular thrust, and it should last less than one-third of systole, less than 50% of systole. This is normal. Do you really get the lift in a tapping apical impulse in mitral stenosis? The LV has gone down.
00:26:20CandidateSir, only the palpable S1. The first heart sound is perceived as the apical impulse.
00:26:24FacultyYou can localise the sound and say that the apex could be here. So you don't get that perpendicular thrust, because the LV has gone down and the RV is in front.
00:26:35CandidateThat should be corrected, sir.
00:26:35FacultyCorrect. There is a difference between a tapping type of apical impulse and a normal one. This is one of the commonest mistakes I am seeing students of today make, because they are not exposed to many cases of mitral stenosis now. But this is a very common case. Go through all this very clearly, in detail; know about the various studies of rheumatic fever and the basics of mitral stenosis.
00:27:02Okay, so you got a normal or tapping apex. Hemodynamically, which among the lesions is ruled out?
00:27:12CandidateSevere AR is out. MS is the most dominant lesion here. AR might be associated, but MS is more dominant.
00:27:16FacultyDue to two reasons. What are the two reasons?
00:27:20CandidateThere is no cardiomegaly, and the apex is of [normal] character.
00:27:24FacultyOkay, go ahead.
00:27:26CandidatePalpable second heart sound; systolic thrill in the right second intercostal space.
00:27:34FacultySystolic, right second intercostal space? Okay.
00:27:43CandidatePercussion: the left second intercostal space is dull, the right heart border is retrosternal, and the left heart border corresponds to the apex. Auscultation: S1 is loud; S2 is narrowly split with a loud P2; no additional sounds; three murmurs.
00:28:06FacultyNo, wait. Just summarise the findings so far.
00:28:11CandidateLoud S1, narrowly split S2 with loud P2...
00:28:11FacultyNo, starting from the blood pressure.
00:28:13CandidateJVP is not elevated. Sinus rhythm. Wide pulse pressure with negative Hill sign [unclear]. No cardiomegaly; the apex is in the normal position, with a normal apical impulse. There is a palpable P2 and a thrill in the right second intercostal space. S1 is loud and S2 is narrowly split with a loud P2.
00:28:37FacultyFrom this, what is your possibility? You said thrill in the right second intercostal space: is it systolic or diastolic?
00:28:51CandidateSystolic thrill.
00:28:51FacultyOkay. From this, what do you suppose, before going to the murmurs?
00:28:56CandidateSignificant MS is there, sir, causing the loud P2, with a normal apex and normal cardiac size. And AR is there, with a flow murmur causing the thrill.
00:29:10FacultyCan a flow murmur cause a thrill in the aortic area? Even severe AR can cause a thrill, but you said severe AR is not there. But a thrill is there. Which thrill is it?
00:29:19CandidateThrill in the aortic area, sir, probably because of AS.
00:29:25FacultyHe has committed with the systolic thrill: probably because of AS.
00:29:34CandidateSince AR is only moderate, I am thinking there will be associated AS also in this case. That's why I want to keep AS and AR with severe MS as my diagnosis at this point.
00:29:49FacultySo AR and AS are also there. So what is the severity?
00:29:49CandidateAS is moderate, sir; AS and AR both are moderate, because the apex is not heaving type, the pulse [unclear] is not there, and the systolic BP is 130, so there is no decapitation. If AR were there with severe AS, there would have been systolic decapitation; that also is not there. But the thrill is there, so there is a functional obstruction to aortic outflow. So moderate AS, moderate AR and severe MS is what I would keep at this point.
00:30:24FacultyOkay, now go to the murmurs. Is the murmur conducted to the carotids?
00:30:24CandidateYes, sir. Coming to the murmurs.
00:30:35A grade 2/4 low-frequency, rough, rumbling mid-diastolic murmur heard shortly after A2...
00:30:41I told: S1 loud, S2 narrowly split with loud P2, no additional sounds.
00:31:05FacultyS1 is loud, you said. So what do you expect?
00:31:09CandidateS1 loud means the MS is more significant, and the valve is pliable, not calcified. The opening snap is not there.
00:31:24FacultyYou were expecting an opening snap?
00:31:24CandidateMaybe it is absent because of the post-PMV status.
00:31:28FacultyWhat happens to the opening snap in this, with AR?
00:31:28CandidateBecause of the increase in LVEDP, the opening snap can be decreased in intensity and can be absent also. The A2-OS interval can decrease.
00:31:47FacultyWill the A2-OS interval decrease, or...? The LVEDP increases, so the opening will be [unclear: possibly 'delayed'].
00:32:04CandidateMurmurs: a grade 2/4, low-frequency, rough, rumbling mid-diastolic murmur, heard shortly after A2 and of long duration, best heard with the bell of the stethoscope in the left lateral position with breath held in expiration, with presystolic accentuation.
00:32:21A grade 3/6 high-frequency, blowing, decrescendo early diastolic murmur, heard in less than 50% of diastole, best heard in the left second intercostal space with the patient bending forward and breath held in expiration. A harsh, rough, grade 4/6 crescendo-decrescendo ejection systolic murmur with early systolic peaking, heard in the right second intercostal space and radiating to both carotids and the apex. Three murmurs are there.
00:32:59There is no murmur of MR. Only the AS murmur is conducted to the apex, sir.
00:33:12Final diagnosis: acquired valvular heart disease of rheumatic etiology, with severe MS, moderate AR and moderate AS, with evidence of moderate pulmonary venous hypertension. No signs of infective endocarditis.
00:33:32FacultyWhat is the evidence of PVH in this patient?
00:33:39CandidateIn the history, she has recurrent dyspnea, and P2 is loud. These are the two main things. No signs of active acute rheumatic fever, with normal LV function, in sinus rhythm, and currently in NYHA class II.
00:34:03FacultyOkay, why do you say normal LV function?
00:34:03CandidateThe apex is normal. MS won't cause LV dysfunction so early. If AS and AR caused LV dysfunction, there would be a sustained apex, and the blood pressure is 130.
00:34:19FacultyCorrect. Okay, you say severe MS. How much LA pressure do you think there is here?
00:34:27CandidateArbitrarily, sir, above 20. Above 20 it is severe MS.
00:34:31FacultyAbove 20? Then are you hearing any crepitations?
00:34:39CandidateBut it will get adapted. In long-standing MS the pulmonary venous lymphatics will improve, and the patient is in the hospital, so diuretics will have been administered. That will mask it.
00:34:50FacultyOkay. No TR?
00:34:57CandidateNo TR.
00:35:01FacultyOr was it there, with the pedal edema she had complained of?
00:35:01CandidateThere is no pedal edema now, sir. She said it was there up to the mid-knee.
00:35:09FacultyWhich manoeuvre will you do to bring out TR, if any?
00:35:14CandidateInspiration can increase it; or leg raising, passive leg raising, can bring out TR.
00:35:23FacultyWhat is that sign called?
00:35:26CandidateCarvallo's sign, with inspiration, sir: it increases with inspiration.
00:35:31FacultyOkay. So: rheumatic heart disease, severe MS, moderate AR, moderate AS, moderate PH, normal LV function, not in heart failure.
00:35:49Okay, just one point I wanted to...
00:35:49CandidateNo, sir, the BP is 130. That's why moderate AR, not severe.
00:35:58FacultyJust one clarification for everybody; all the students are here. While describing a murmur, should we speak of pitch or should we speak of frequency? In the books it is low-pitched, medium-pitched and high-pitched, but you kept on saying frequency. Pitch is what you are hearing; frequency is what you are recording and assessing on an instrument. So confine yourself to the standard. What is the relation between pitch and the murmur normally?
00:36:35CandidateBlowing will be high pitch, harsh will be medium pitch, and low, rough will be low pitch.
00:36:45FacultyWhat about flow? Which will be low?
00:36:45CandidateIncreased flow means lower frequency, sir; increased gradient means higher. Gradient is directly proportional, and flow is inversely proportional, to the frequency or pitch.
00:36:56FacultyAortic stenosis?
00:37:01CandidateThe gradient is high, but, as in AR, the flow also is high. So it comes under medium.
00:37:09FacultyBut you say harsh. Do you mean high pitch or low pitch?
00:37:12CandidateIt is mixed; medium pitch.
00:37:14FacultyHarsh is mixed. What is low pitch, medium pitch and high pitch, frequency-wise?
00:37:26CandidateIt is given in [unclear]: less than 150, [unclear figures], 125 to 300, above 300.
00:37:37FacultySo you can remember it as: less than 150, 150 to 300, and above 300.
00:37:44The diastolic murmur of MS: you said frequency. What will its frequency be? Is it easy to record or difficult to record?
00:37:51CandidateLow frequency, sir. It is difficult to record.
00:37:54FacultyDifficult to record. Nowadays there is one [digital stethoscope, name unclear]. Have you seen that advertisement? You put it on and you get the ECG and the phono both at the same time. You will not get an MDM. You will get every other murmur except the MDM, because it is low frequency, low pitch. Okay, you proceed further.
00:38:22CandidateShe is symptomatic, functional class II right now, and she has palpitations. So I would like to confirm the palpitations and rule out paroxysmal AF in her, and go ahead with an ECG, echo and X-ray to characterise the lesions properly. In this case, if the mitral valve is still pliable and BMV is anatomically feasible, then, if the AS and AR are moderate, only BMV. If either the AS or the AR needs intervention, or BMV is not feasible, then she will have to go for DVR.
00:39:05FacultyThat we will discuss when you come to management. Okay.
00:39:13So what do you expect on the ECG?
00:39:13CandidateOn the ECG I would expect the MS findings to predominate. The rhythm will be sinus, because it is regular, and I would expect LA enlargement.
00:39:25FacultyAnd what about the axis?
00:39:31CandidateThe axis would be...
00:39:34FacultyThere are two reasons why the axis should be in a particular direction.
00:39:34CandidateSince AS and AR are both there, with both concentric and eccentric hypertrophy, I would say left axis deviation.
00:39:40FacultyYou said the dominant lesion is mitral stenosis, with PH. Mitral stenosis causing RVH and PH gives right axis deviation. That will determine which is the dominant lesion.
00:39:55Do we expect LVH in this patient?
00:39:55CandidateNo, sir, less likely, because MS is more predominant.
00:40:05FacultyWhat is the earliest ECG sign of MS?
00:40:14CandidateLA enlargement.
00:40:16FacultyCorrect. But before that? What about the P-wave axis?
00:40:24UnclearThe P-wave axis should be less than [unclear] deviation of P; P inverted in lead III. That is the earliest sign.
00:40:38FacultyOkay, take up the investigations.
00:40:43CandidateWe'll go to the investigations, sir.
00:40:47FacultyYou have exceeded the time, is it? Okay. Show the ECG.
00:41:30So you said you will go ahead with BMV if the aortic valve lesions are not that significant. Will there be a problem in doing the BMV?
00:41:42CandidateAfter BMV the output will increase. The MS might be masking both the AS and the AR. So we should be careful in assessing; we can't use the normal methods.
00:42:00FacultyHow do you assess AS severity in the presence of severe MS?
00:42:09CandidateThe valve area: the aortic valve area by planimetry, and the continuity equation would be better in this case. Other estimates, the Doppler gradients, will be affected by the severe MS and the low-flow condition. If there is a discrepancy between the flow and the area, then we have to approach it like low-flow, low-gradient AS.
00:42:36FacultyYou have done BMV, or assisted? How do you know from the LA pressure tracing whether your BMV is going to be successful or not?
00:42:47CandidateFrom the LA tracing, whether the results will be good or not, after...
00:42:53FacultyBefore. You have got the LA pressure tracing, not LA-LV, before doing the BMV, from the hemodynamic monitor. Okay, we'll come to that later.
00:43:07Candidate12-lead ECG with half standardisation, 25 by 5...
00:43:07FacultyVery good, half standardisation.
00:43:15CandidateRegular rhythm, heart rate of around 80 beats per minute. P wave...
00:43:23FacultyThis is standard, no? This is normal standard.
00:43:26Unclear25 by 5 is written below.
00:43:31FacultyNo, this is half standard. Okay, go ahead.
00:43:35CandidateRegular sinus rhythm. P wave: there is left atrial enlargement, according to the Morris index. Then the QRS axis is...
00:43:59FacultyMacruz index and Morris index you should know. Yes, okay, go ahead.
00:44:03UnclearThe P wave will be double this; that is half standardisation.
00:44:07FacultyBut is it really half standard? The standardisation box is there on the left, it's half standard, and at the bottom also it is written 5 mm per millivolt. Oh, 5 mm is written. Okay. It is written; that's right.
00:44:42Yes, okay. There is obvious left atrial enlargement, and the right atrium also is enlarged; biatrial enlargement is there. The axis is...
00:44:55CandidatePlus 40 degrees.
00:44:55UnclearThen 40, yes. aVL is [unclear]... 15 to 30... [unclear] 55, but towards the positive side, around 15.
00:45:22CandidateThen there is LVH also, sir. Comparing V2 and V6, according to the Sokolow-Lyon index, LVH is there.
00:45:29FacultyAnd you want to consider the severity of the aortic valve disease?
00:45:37CandidateYes.
00:45:41FacultyBut the BP, the pulse, everything is against it. So by ECG, LVH is there. Okay. But is it a pressure overload or a volume overload?
00:45:54CandidateThere's no Q wave; this is pressure overload.
00:45:57FacultyBut the T is not inverted.
00:45:57CandidateT is not inverted. There is no strain.
00:46:13FacultyOkay, I don't think we can get anything more. It is sinus rhythm with no [unclear], no right axis deviation, no RVH; so it is sinus rhythm with only some signs of LA enlargement. Okay, next: X-ray.
00:46:31When was this taken? Describe this X-ray.
00:46:35CandidateChest X-ray, PA view, overexposed, with rotation to the right side.
00:46:40FacultyAP view, taken when she was in failure in hospital. First describe the lung fields.
00:46:44CandidateIn the lung fields there is a bat-wing appearance: grade 3 pulmonary venous hypertension, pulmonary edema. The CT ratio, although it is an AP film, is around 0.65.
00:47:10The right atrial border extends only two intercostal spaces; there is no obvious right atrial enlargement... It's two and a half intercostal spaces, so right atrial enlargement is there. Left atrial appendage: LA enlargement is there. Splaying of the carina is not seen; the bronchus is not clearly visible. There is no double density. Both RA and LA enlargement are there, and cardiomegaly of LV type is there, with pulmonary edema, grade 3 PVH.
00:47:51FacultyAny other X-rays from when the patient was not that sick?
00:48:13Okay, yes, this is much better. This is much better. This is PA view; this is also overexposed. What are the situations in which this patient can present with the previous X-ray picture?
00:48:25CandidateAF, severe anemia; AF is the most common condition.
00:48:32FacultyOkay.
00:48:36CandidateIn this patient, what is the date of the X-ray?
00:48:42FacultyThe 14th; recent only.
00:48:42CandidateOkay. The cardiothoracic ratio is 0.65. There is cardiomegaly of LV type, right atrial...
00:48:53FacultyNo, I don't think it is 0.6. LV type... Stop going down to the [unclear].
00:49:04CandidateRight atrial enlargement is there, and straightening of the left heart border. Coming to the lung fields, grade 1 cephalisation is there: grade 1 pulmonary venous hypertension.
00:49:15FacultyIs there LAE or not? Is there LAE?
00:49:22CandidateThere is straightening of the left heart border, but the carina... and the double density is not clearly seen.
00:49:26FacultyDouble density is not very clear.
00:49:37Please explain: so the aorta is dilated?
00:49:42CandidateThe descending aorta.
00:49:47FacultyWhy are you seeing the descending aorta there? Okay, fine.
00:49:59Okay, any calcification you will look for in this patient, with a very long-standing history of mitral stenosis?
00:50:07CandidateCalcification in the mitral area; the left atrial wall also can be calcified in very old patients with long-standing mitral stenosis.
00:50:17FacultyCan some calcification occur in the lung fields in very chronic mitral stenosis, with chronic pulmonary venous hypertension? What will happen? What is that called? It is rare only, very rare.
00:50:36CandidatePulmonary hemosiderosis can occur.
00:50:36FacultyOkay.
00:50:45Okay, from the ECG, what is your [unclear]?
00:50:49CandidateYes, I would like to evaluate the AS. Maybe the severe MS was masking the AS severity in my case, but the apex was still not heaving type.
00:50:57FacultyOkay. The position of the apical impulse and its character is the most important determinant.
00:51:01CandidateYes. In both AS and MS it would have been the same position. But the thrill was there in the right second intercostal space; that's why I kept AR, AS and MS.
00:51:16FacultyOkay, go to the echo.
00:51:20CandidateTransthoracic echo, parasternal long-axis view. There is concentric LVH; the AML is...
00:51:27FacultyHow will you know whether your BMV is going to be successful or not from this view?
00:51:34CandidateThe pliability: the doming and pliability of the valve can be assessed in this view.
00:51:46FacultySo first of all, in diastole, the separation between the two tips of the anterior and posterior leaflets [unclear]. What is the normal, or the value below which it is considered severe mitral stenosis?
00:52:01Candidate5 mm [unclear].
00:52:07Unclear[unclear figures: '0.5, 0.7, 0.8'].
00:52:07FacultyYes, okay. Read this echo.
00:52:16What's this first one? No, okay, read this echo. Which chambers are enlarged?
00:52:25He went to concentric LVH; that was the first thing he was telling. The most important thing here is the dilated LA, and the aortic valve is affected.
00:52:33CandidateYes. There is doming of the AML and restricted movement of the PML. Small, spotty calcification at the tip of the PML.
00:52:50FacultyWhile you are trying to explain, don't go to the concentric LVH here. The main pathology has to be explained first, rather than going to concentric LVH. What about the RV? Is it dilated? Because you are considering TR.
00:53:04CandidateYes, sir. I would have to measure it, but it looks dilated.
00:53:09FacultyThe RV is not that dilated. But RV function definitely is normal; it looks normal only. Okay, go to the next one.
00:53:20CandidateColour Doppler across the mitral and aortic valves. There is mild subvalvular disease, mild to moderate...
00:53:33FacultySevere subvalvular disease? No. One more important thing: you are planning to do some intervention. Are you happy seeing this view? By the way, I will not comment on the subvalvular apparatus in this view; I am hardly seeing it. You have to see the leaflet, from the tip of the leaflet to the tip of the papillary muscles, the papillary muscles and the ventricle; then I will comment on the subvalvular apparatus. You need the information on all this before you can comment. Do not comment on it here.
00:54:09The most important thing here is the long jet of AR, crossing the tip of the AML and going right up into the ventricle. You have to open it up; then you have to see the LVOT properly and take the width. And there is no mitral regurgitation; that is the one that matters when you are planning BMV. The valve is not that calcific, the AML is still doming, there is reduced leaflet separation, and MR is not there, in this view at least. Okay.
00:54:46For the AR jet, is the width important, or is the length more important?
00:54:52CandidateThe width: the width-to-LVOT ratio is more important.
00:54:52FacultyHow much ratio?
00:54:52Candidate65%. More than 65% is severe AR.
00:55:00And there is concentric LVH. Parasternal short-axis view: concentric LVH; there is commissural fusion, bicommissural fusion, with thickening of the mitral leaflets and calcification. There is no dense calcification of the mitral valve; some specks of calcification are there in the AML. The commissures are free of calcification, and both commissures are fused. This looks suitable for BMV.
00:55:30FacultySuitable for BMV.
00:55:30CandidateI would like to confirm that there is no MR [unclear] and no clot in the other images.
00:55:40FacultyOkay, forward. Which is more reliable for the mitral valve: Doppler, or planimetry?
00:55:45CandidatePlanimetry. Short axis at the papillary muscles: LV function is normal.
00:56:01FacultyOkay, forward.
00:56:16Yes, what are you seeing?
00:56:16CandidateThis is the short-axis view at the aortic valve. The leaflets appear slightly thickened.
00:56:26FacultyIs it restricted? You said aortic stenosis. You should see the opening, not the closure.
00:56:35CandidateThe aortic valve area is decreased. There is no calcification of the aortic valve [unclear].
00:56:40FacultyWhat other important structure are you seeing? You are planning a procedure, and that will help.
00:56:48CandidateThe left atrium and appendage are seen; there is no clot.
00:56:52FacultyYes, the appendage is very clearly seen; it is free of any clot. Okay. The aortic valve is not grossly thickened, but it is thickened, with restricted opening. Okay, what is that structure? The other white structure you are seeing?
00:57:08UnclearSmall... okay.
00:57:13FacultyYou are planning balloon mitral valvotomy again. Would you like to do a transesophageal echo or not, as she is in sinus rhythm, in this case?
00:57:23CandidateTEE, to rule out clot.
00:57:26Faculty[unclear] is not able to see the image properly. It is mandatory to do a TEE before, except probably in pregnant patients undergoing BMV in sinus rhythm, where you can probably avoid it. Otherwise it is mandatory to do a transesophageal echo to rule out clot. And we are doing it now for the second or third time.
00:57:46CandidateYes, and she had a history of palpitations, and we don't know whether she had paroxysmal AF, especially with this [unclear].
00:57:56FacultyThe small structure, the small white structure... Left, [unclear]. Yes, go ahead. Okay.
00:58:13Apical four-chamber. Yes, go ahead.
00:58:20CandidateApical four-chamber view: LA enlargement and concentric LVH. Mitral valve: there is thickening of the anterior leaflet and restricted posterior leaflet motion. Subvalvular disease is moderate: moderate subvalvular thickening. I would have to see the colour Doppler.
00:58:43FacultyThe LVH is not very gross. Borderline. Yes, okay, go ahead.
00:58:52CandidateSevere... There is increased turbulence in systole in the subvalvular area, and the AR also [unclear]; this is not focused completely.
00:59:05FacultyOkay. Show the Doppler, the mitral Doppler.
00:59:18CandidateContinuous-wave Doppler across the mitral valve: mean gradient of around [unclear].
00:59:23FacultyYou have reported the mitral valve gradient. What important thing is missing? It could be calculated, but it has not been. What is it? V max, V mean, everything is written, but one thing is not written.
00:59:38CandidatePressure half-time.
00:59:42FacultyNo. See, the mitral valve gradient always depends upon the heart rate. You have to mention the heart rate. Okay. Something is written. Okay, 69. Okay, here it is.
01:00:09CandidateSir, the mitral valve gradient is not that high.
01:00:09FacultyYes. What is the orifice area?
01:00:19CandidateThe 2D valve area was not done.
01:00:19FacultyNo, it must have been done.
01:00:23UnclearThe measured view was not that one.
01:00:28FacultyWhat does it say? 0.7. Okay.
01:00:36What is low-flow, low-gradient mitral stenosis?
01:00:39CandidateIn cases like this patient, with a low heart rate, the stenosis is severe, but because of decreased flow the gradient is low, only 7 in this condition. On exercise we can again assess for symptoms, murmur and gradient.
01:00:55FacultyAgreed. There is an entity called low-gradient MS; there are a lot of series on that. Nowadays, when we do BMV in our hospital, the patients are all above 60. The young patients with very pliable valves, that era is over. Now they all have low gradients with a severely reduced 2D valve area.
01:01:22What is the severity of AR?
01:01:22CandidateAR is moderate in this: the jet is occupying less than 50% of the LVOT. To quantify it, I would like to see the pressure half-time and flow reversal.
01:01:41FacultyOkay, they have given you the pressure half-time.
01:01:47Candidate430. It is moderate only; less than 200 is severe.
01:01:51FacultyAround that it is mild only; mild to moderate.
01:01:58Okay, so what is this?
01:02:02CandidateThis is the AS Doppler: around 32. Since it is low flow and the cardiac output is low... 4 metres [unclear].
01:02:08FacultyHow can it be that, sir? How do you know from this tracing that it is not flow-related but organic aortic stenosis?
01:02:17CandidateIt could be due to the AR flow. The shape of the envelope...
01:02:22FacultySo, if it is [unclear]-shaped and peaking in the early part of systole, it is probably not that severe; but if it peaks late [unclear]... Clinically also you will get a slow-rising, late-peaking murmur. So it is like an open envelope and a closed envelope, as we call it.
01:02:55Do you think the AS is severe or not severe in this case?
01:02:59CandidateNot severe. The murmur is grade 4/6, but it is early peaking, so flow could also be contributing, and the mean gradient is only 32 [unclear: '30, 32']. The AR can increase the flow. So it comes under moderate only: less than 40.
01:03:14FacultyOkay, so what is your final diagnosis after all this?
01:03:24There's a question on the group: can he use the pressure half-time for AR when MS is there? Somebody asked on the group: is it valid?
01:03:31UnclearNo, it cannot be used [unclear].
01:03:35FacultyI think it cannot be relied on. Can pressure half-time be relied on for AR severity when MS is there? No, it is difficult. MS is there, so we can't use it; you couldn't rely on that. Also, you can't depend on one parameter. You should not decide on a single parameter.
01:03:55Okay, so what is the final diagnosis? I think our time is going.
01:03:55CandidateSevere MS, moderate AS, moderate AR, normal LV function, in sinus rhythm, with moderate pulmonary venous hypertension.
01:04:10FacultyOkay, what will you do for this patient?
01:04:10CandidateI would consider BMV for her symptoms, but there is a risk that the [unclear] can become significant after BMV. We should reassess the patient.
01:04:26FacultyOtherwise what will you do? If you are not considering BMV, what is the other option?
01:04:34CandidateDVR, sir.
01:04:34FacultyWhat is the mortality of DVR?
01:04:39CandidateAround 9 to 10%.
01:04:39FacultyOkay. What is the longevity of a patient who is coming for DVR? I don't know: 50 years, this socio-economic background, 10 years, 20 years? More than 60% mortality after DVR; high mortality on follow-up.
01:05:02On the LA pressure tracing, when you see it before BMV: if you see a prominent c wave, just as you see on the right side, it means your balloon [unclear]. The presence of the c wave tells you that the descent of the base of the mitral valve is quite good; hence it will open well. That's what you feel. There are other parameters also: DE amplitude more than 18 by M-mode, and many other parameters.
01:05:31Okay, this patient is going home after a BMV; you have done a successful BMV. What is a successful BMV?
01:05:36CandidateAfter BMV the valve area should increase by 50%. Valve area 0.7 and a gradient of [unclear]... An area increase of 50%, or more than 1.5 cm², without any increase in mitral regurgitation of more than 2 grades.
01:05:53FacultyOkay, and this patient is going home after BMV. What is your prescription?
01:06:00CandidateFor heart rate, a beta-blocker after BMV.
01:06:00FacultyBeta-blocker [unclear]. Second option: there are other drugs given for rate control in mitral stenosis other than beta-blockers.
01:06:08CandidateCalcium channel blocker.
01:06:11FacultyCalcium channel blocker. Any other drug tried in India? There are so many Indian studies.
01:06:15CandidateIvabradine.
01:06:18FacultyIvabradine. There are two or three Indian series; all of you should know them.
01:06:23Okay, beta-blocker. Then, not for this case, but I will just ask you for aortic stenosis: what is the value of the dimensionless index in the assessment of severity?
01:06:31Candidate0.25. If it is less than 0.25, it is severe AS.
01:06:35FacultyOf course, it will not be that here.
01:06:40Okay, what are the drugs, you said?
01:06:40CandidateBeta-blocker; then, since she has pulmonary venous hypertension, I would prefer diuretics also; then, if sinus rhythm... if AF, then [unclear].
01:06:51FacultyNo, these two... We don't give prophylaxis?
01:06:55CandidateProphylaxis, considered lifelong.
01:06:59FacultyWhich is the best prophylaxis: intramuscular, or is oral better? What is the event rate? How much will you give?
01:07:08CandidateLess than 27 kg...
01:07:08FacultyNo, she is an adult. You said BMI 24.
01:07:12Candidate1.2 million units every third week, sir; every 21 days.
01:07:16FacultyOkay. Suppose it is not available; then the next best? It is not available, and in Kerala nobody is giving that. Then oral penicillin. What are the two preparations available, and which is better?
01:07:34CandidatePenicillin V and penicillin G. Penicillin V is preferred: 250 mg BD [unclear: '500 mg BD'].
01:07:40Unclear[unclear] for chronic prophylaxis.
01:07:45Candidate400 mg BD, sir.
01:07:45Faculty400 mg BD is penicillin [unclear]... TID? No, that is why it is called BD. Then why are you giving it BD? The name itself is printed [unclear]. Then why are you giving it BD?
01:08:01CandidateSir, you said you give 400 mg BD for prophylaxis; the other is for treatment.
01:08:04FacultyTreatment, okay. If that is not available, then?
01:08:09CandidateAzithromycin, erythromycin.
01:08:09FacultyNo, penicillin: there are two preparations. Penicillin G can be given. What is the dose? Which is available?
01:08:18Unclear[unclear brand name] is the one which is available. Now it is called Pen[unclear], 250 BD.
01:08:24FacultyPenicillin is not available, or she is allergic to penicillin. What else?
01:08:31CandidateNext, azithromycin is not [unclear]. Sulfadiazine is recommended, [unclear: possibly 'one gram'].
01:08:42FacultyOkay, I will... thank you.
01:08:45But what are the two or three recent trials in RF secondary prophylaxis that you named?
01:08:50CandidateRecently, in 2022, the GOAL trial compared prophylaxis in subclinical carditis. The recurrence rate of rheumatic fever was 8% in those who did not receive any prophylaxis and 0.8% in those who received it. In both arms the regression was the same; it didn't change. The regression was the same, but the recurrence was 8% versus 0.8%. The [unclear] trial compared IM with oral, sir; that study has yet to be published.
01:09:22FacultyPublished. And what's the alternative hypothesis of rheumatic fever? Have you read that?
01:09:30CandidateThe alternative hypothesis: besides molecular mimicry, the older alternative hypothesis is that it is inflammatory, not just an autoimmune reaction. There is an article which [unclear].
01:09:43FacultyWhat is the newer advance in chronic prophylaxis?
01:09:47CandidateVaccines...
01:09:47FacultyVaccines are being developed, but not that: penicillin prophylaxis. What is depot penicillin?
01:09:52CandidateThere are some penicillin preparations being tried, once in 3 months; you can give one for up to 6 months. It is given as a depot injection.
01:10:02FacultyWhat is the role of colchicine?
01:10:09CandidateIf rheumatic pericardial involvement is there, then you can...
01:10:09FacultyNo, in rheumatic heart disease. Any study done from any centre? An Indian centre?
01:10:21CandidateA trial from GB Pant [unclear]; it came in JACC last year, in all RHD.
01:10:28FacultyYou said azithromycin. Any RCTs done on azithromycin in rheumatic fever?
01:10:36CandidateNot that I know.
01:10:36FacultyWe have done an RCT on azithromycin once weekly, but it was a failure. It was a negative trial; we have published it in the Indian Heart Journal. [unclear] two patients out of [unclear] had recurrence of throat infection, not rheumatic fever. That was a failure, right?
01:10:54Okay, but your assessment: I think he has said it very well. It is a simple case, no doubt, but in a simple case people always falter, and it is a little difficult in the exam. But you have answered very well. Very good. Your [unclear] also is very good; very good and confident. I think this is the way you should present. Good presentation. Come on, give him a big hand.
01:11:21CandidateThank you, sir.
01:11:21FacultyThanks.
01:11:21CandidateThank you, sir. I thank all the teachers for this.
01:11:26FacultyI am really sorry, sir, we are going to make you talk again. Can you just continue the OSCE? Sorry for this. And all of you will have to answer now, so that he talks less. We will fix the laptop. The next presenter will be presenting after the tea break; he is here. The presenter of the last case is also around. She is here, right? She is there.
01:12:21They will not get a break, sir, but they'll talk more this time. I'm really sorry for this.
