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 valve annuloplasty the cardiac cycle. These changes are primarily due to the dynamic motion of the surrounding mitral valve annulus, a collageneous structure which attaches the mitral leaflets and the left atrium to the ostium of the left ventricle and the aortic root. Throughout the cardiac cycle, the annulus undergoes a sphincter motion, narrowing down the orifice area during systole to facilitate coaptation of the two leaflets and widens during diastole to allow for easy diastolic filling of the left ventricle. This motion is further enhanced by a pronounced three-dimensional configuration during systole, the characteristic saddle shape. These changes throughout the cycle
