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.
One of the most common disease of the mitral valve is known as mitral valve prolapse. In this condition one or both of the mitral valve leaflets swings too far backwards during each heartbeat such that the leaflets do not close properly, allowing blood to leak between them.
