Double-Orifice Mitral Valve Anomaly

A 38-year-old woman was admitted to our clinic with exercise dyspnea, in whom transthoracic echocardiographic examination was done because of a systolic murmur. Isolated double-orifice mitral valve with a grade 2/4 mitral insufficiency and mild mitral stenosis was found at transthoracic echocardiography. Isolated double-orifice mitral valve is a rare congenital malformation of the mitral subvalvular apparatus. It should be considered during echocardiographic evaluation of mitral stenosis and/or mitral insufficiency. (Türk Kardiyol Dern Arş 2004; 32: 390-392)
