 Hello, I am Dr. Devananda, Head of the Department of Cardiac Surgery at Manipal Hospitals. I have been practicing cardiac surgery for the last 18 years. We know that replacement, unless it gets into trouble, generally lasts longer. Now how long a repair would last? It again depends on the nature of the valve itself and the pathology, what had caused the mitral valve leak and for which we had done a repair. Now if it is a rheumatic background, where secondary to rheumatic heart problems, somebody had a valve leakage and that we have repaired it, these repairs generally do not last very long because rheumatic heart problem is a kind of a progressive problem. So these repairs probably would work for a couple of years and they would fail. One definitely requires either replacement, generally replacement following a rheumatic heart problem repair. Now in the country when you repair a degenerative valve, these repairs are definitely long lasting. If underlying pathology of the valve is straight forward and simple, like only a part of the segment of the mitral valve is leaking, the long term results of these repairs are very, very good. Like end of 15 to 20 years, one remaining, good with the same repair, freedom from another intervention of re-operation is almost 85 to 90 percent, which is fantastic, no valve can match that result. Now in the country, if I repair a valve with multi-level pathology, you have got different kind of problems, you try to correct all that, our results of repair probably may not be the best like a single segment or one or two segments repair. So multi-segment repairs probably tend to last little less compared to a single segment repair.
