    00:01 So, let’s talk just for a few seconds about the final valve, the tricuspid valve. The tricuspid valve can be affected in severe rheumatic heart disease, but these days, that is very rarely seen. One can have congenital tricuspid stenosis, something that often requires repair in childhood. But, most commonly, we see tricuspid regurgitation when patients develop heart failure that results in dilatation and poor functioning of the right ventricle.

    00:30 What happens then is the right ventricle stretches the valve… ring a little bit so that it leaks and often, we call this functional tricuspid regurgitation. Why? Because it gets better when we treat the heart failure and the heart shrinks down a little bit.

    00:47 Occasionally, when a patient is being sent for valve replacement, either mitral valve or aortic valve replacement, there is such severe heart failure that the tricuspid valve has been markedly stretched open and in that setting, either tricuspid valve replacement or more commonly, a plastic surgical operation in which the valve is tightened up is done by the surgeons at the same time that they replace either the mitral, aortic valve or possibly both. In most cases, the functional… a tricuspid regurgitation gets better when the patient’s heart failure is treated. Just an echo here to show you again, an example of… severe tricuspid regurgitation, you can see there the rainbow image of a large jet of tricuspid regurgitation going down into the right ventricle in this patient with functional tricuspid regurge secondary to heart failure.

    01:46 So, in conclusion, valvular heart disease is still with us. It’s still quite common, but there has been a major change in the form of valvular heart disease over the last four, five decades because of the aging population and because of the near eradication of rheumatic fever. Most of the patients we see in the hospital these days have calcific atherosclerotic aortic stenosis and most of them are quite elderly.

    02:14 We still see a fair number of people with mitral valve disease, but it’s usually again, congenital. Patients with myxomatous or prolapsing mitral valve disease, that’s a congenital form. Usually, those patients do well with medical therapy and they don’t require a valve replacement or repair except when a portion of the valve tears, one of the cords tear and the patient has acute mitral regurgitation.

    02:38 The elderly population with atherosclerotic aortic stenosis often have a lot of co-morbid conditions. Of course, theyre elderly and so, they may be quite complicated with lung disease and liver disease and so forth and they often represent a real challenge to the cardiologist. Fortunately, we are now able to replace the valve with a catheter procedure which is much less invasive compared to opening the chest and for many of these elderly and frail individuals, that’s a very good alternative.

    03:09 The various forms of mitral valve disease can come from a variety of sources. For example, endocarditis and a whole bunch of other conditions, but the commonest is the myxomatous one. Mitral valve repair in these patients is preferred to mitral valve replacement except in very elderly individuals. Endocarditis is often a problem. Any injury to the valve makes that valve more susceptible to a bacterial infection and with the bacterial infection, you often have an acute leak, either acute aortic regurgitation or acute mitral regurgitation. These patients need urgent surgery. Well, that takes us through the entire course of valve disease. As you can see, it’s quite complicated with a number of different lesions, but in the end, it’s aortic stenosis that is the most common these days.

    04:01 Thanks very much for being with me today. I look forward to speaking with you in the next segment.

    wonderful, thank you Doc I spent quality time during these lessons

    Concise but still very thorough
    By Rachel P. on 10. November 2019 for Tricuspid Regurgitation – Valvular Heart Disease

    The valve course was very helpful. Concise but still very thorough in covering pathology, clinical presentations, and treatment courses. Great presentation, Dr. Alpert!

    Good Explanations
    By Thiviet N. on 01. July 2019 for Tricuspid Regurgitation – Valvular Heart Disease

    Dr. Alpert's videos really helped me with my studies. The explanations were clear and easy to follow. Thanks.

    Inaudible at times.

    There were some points in the lecture were the lecture was in audible. I read along and there were just dots in the space that i didn't understand what was being said. Over all it was very helpful
