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 native annulus and some of its natural dynamics. The goal of semi-rigid rings is to maintain coaptation and valve integrity during systole, while allowing for good hemodynamics during diastole. Rigid rings are designed to provide rigid support in large dilation and under high-pressure. Annuloplasty devices usually come in different sizes. The surgeon can estimate the dimensions of the patient’s mitral valve and decide on an appropriate ring size. Depending on the disease etiology, different approaches are taken. Surgeons can decide to "undersize" the device, "truesize" the device, or "oversize" it. Annuloplasty devices are classified by the U.S. Food and
