Mitral valve replacement

From Wikipedia, the free encyclopedia

Mitral valve replacement is a cardiac surgery procedure in which a patient's mitral valve is replaced by a different valve. Mitral valve replacement is typically performed when the valve becomes too tight (mitral valve stenosis) for blood to flow into the left ventricle, or too loose (mitral valve regurgitation) in which case blood can leak into the left atrium and back up into the lung. Some individuals have a combination of mitral valve stenosis and mitral valve regurgitation; this combination can also be treated with replacement of the valve.

Currently, mitral valve replacement is an open surgical procedure, requiring placing the patient on cardiopulmonary bypass to stop blood flow through the heart as the heart is opened up to perform the procedure.

There are a number of choices of the type of valve that the native mitral valve can be replaced with. These include tissue valves and metallic valves.
