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 of the regurgitant flow at the level of the valve. This is known as the regurgitant orifice area, and correlates with the size of the defect in the mitral valve. One particular echocardiographic technique used to measure the orifice area is measurement of the proximal isovelocity surface area (PISA). The flaw of using PISA to determine the mitral valve regurgitant orifice area is that it measures the flow at one moment in time in the cardiac cycle, which may not reflect the average performance of the regurgitant jet. The treatment of mitral insufficiency depends on the acuteness of the disease
