Mitral valve annuloplasty double by the year 2030. Every year, 300,000 people worldwide undergo open heart surgery for mitral valve repair, 44,000 people in the US alone. Since it was initially established 40 years ago by Professor Alain Carpentier, mitral valve annuloplasty has been continuously improved and is considered the gold standard for the treatment of most etiologies of mitral valve dysfunction today. The goal of mitral valve annuloplasty is to regain mitral valve competence by restoring the physiological form and function of the normal mitral valve apparatus. Under normal conditions the mitral valve undergoes significant dynamic changes in shape and size throughout
Mitral insufficiency broad, notched P waves in several or many leads with a prominent late negative component to the P wave in lead V, and may be seen in MI, but also in mitral stenosis, and, potentially, any cause of overload of the left atrium. Thus, "P-sinistrocardiale" may be a more appropriate term. The degree of severity of MR can be quantified by the regurgitant fraction, which is the percentage of the left ventricular stroke volume that regurgitates into the left atrium. where V and V are, respectively, the volumes of blood that flow forward through the mitral valve and aortic valve
