Mitral valve prolapse differs from mitral valve stenosis. In mitral valve stenosis, the mitral valve is stiff and constricted. In mitral valve prolapse, the valve slips backward due to the abnormal size of or damage to the mitral valve tissues. For most people with mitral valve prolapse, the cause is unknown. Mitral valve prolapse can run in families.
