Bioprosthetic valves are made from animal tissue (called a xenograft) or taken from the human tissue of a donated heart (called an allograft or homograft). Sometimes, a patient's tissue can also be used for valve replacement (called an autograft).
During valve repair or replacement surgery, the breastbone is divided, the heart is stopped, and blood is sent through a heart-lung machine. Because the heart or the aorta must be opened, heart valve surgery is open heart surgery.
Percutaneous mitral valve repair (MVR) is a new treatment being investigated to determine the effectiveness of a percutaneous approach for treating mitral valve regurgitation. The procedure is performed using echocardiography in the cardiac cath laboratory.
