Mitral valve replacement replacement include lower surgical mortality (1-2% for repair versus 6-8% for replacement), lower risk of stroke, lower rate of endocardial infection, and improved long-term survival. Patients who receive a valve repair stay on the same survival curve as the normal population. After mitral valve repair, blood thinners are not required; however, lifelong maintenance on blood thinners is required after mechanical mitral valve replacement. Mitral valve surgery can now also be performed robotically although the procedure may take longer. Most patients can endure surgery without complications; however, there are some whose heart functions are too weak to withstand surgery. Non-surgical approaches
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
