closed repair of stenotic mitral valve comissurotomy (cmvc) or percutaneous transvalvular mitral valve comissurotomy (ptmc)

the history of closed mitral valve comissurotomy (cmvc) and its indication is discussed in this article. however many of the patients undergo (ptmc) these days as a new procedure and of course more effective and easier way whenever is indicated, yet, (cmcv) should be considered as a simple, and effective surgery when indicated, especialy in third world countries in which economical, social and personal point of views are important.my main point in this article is to encourage younger surgeons and colleagues to pay more attention to this kind of cardiac surgery, which at the first glimpse seems difficult and perhaps dangerous to untrained and unskillful hands!
