Mitral Valve Replacement

Mitral valve replacement has been superseded by mitral valve repair as the treatment of choice for all forms of mitral regurgitation. There are several reasons to prefer a mitral valve repair to a replacement (such as avoidance of anticoagulation, lower risk of endocarditis, better ventricular function, desire to keep one’s own tissue), but from an epidemiological viewpoint, the prime value of the repair operation lies in the incontrovertible superior long term outcomes of repair relative to replacement. Almost all studies comparing valve repair and replacement for regurgitation have found a survival benefit for repair in a diverse array of clinical settings.
