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 during a cardiac cycle. Methods that have been used to assess the regurgitant fraction in mitral regurgitation include echocardiography, cardiac catheterization, fast CT scan, and cardiac MRI. The echocardiographic technique to measure the regurgitant fraction is to determine the forward flow through the mitral valve (from the left atrium to the left ventricle) during ventricular diastole, and comparing it with the flow out of the left ventricle through the aortic valve in ventricular systole. This method assumes that the aortic valve does not suffer from aortic insufficiency. Another way to quantify the degree of MR is to determine the area
