Synopsis

Dysfunction of the mitral valve characterized by incomplete valve closure, resulting in systolic flow of blood from the left ventricle to the left atrium. Mechanisms include leaflet prolapse, endocarditis, congenital anomalies, ischemia, dilated cardiomyopathy, and rupture of chordae tendineae or a papillary muscle. The resultant increase in left atrial pressure often results in atrial fibrillation, dyspnea, and/or congestive heart failure.
