Mitral valve replacement the patient on cardiopulmonary bypass. In a study of 99 patients who had mitral valve surgery for regurgitation from January 1990 to June 1996, overall mortality was 4%, which included 3 operative deaths and 4 late deaths. Overall 5-year survival rate was 92%. With mitral valve replacement surgery, there are risks such as bleeding, infection or reaction to anesthesia. Risks depend on a patient’s age, general condition, specific medical conditions, and heart function. Neuropsychological and psychopathologic changes following mitral valve replacement surgery have been recognized from the very beginning of modern heart surgery. Variables correlated with nonpsychotic mental disorder after
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
