A leaky mitral valve, or mitral regurgitation, can develop when the valve flaps (called leaflets) do not close effectively. This can happen either because the valve flaps are scarred or defective, or because the heart has become enlarged, stretching the valve opening so much that the flaps no longer meet in the center.
Mitral valve prolapse and regurgitation. The mitral valve separates the two chambers (atrium and ventricle) of the left side of the heart. In mitral valve prolapse, the leaflets of the mitral valve bulge (prolapse) into the left atrium like a parachute during the heart's contraction.itral valve regurgitation causes. Mitral valve regurgitation is classified as primary and secondary. Primary mitral valve regurgitation is caused by an abnormality in the mitral valve. Secondary mitral valve regurgitation is caused by an abnormality in the left ventricle of the heart.
