Double-orifice mitral valve: report of two cases.
Two cases of double-orifice mitral valve are reported. The first case was associated with coarctation of the aorta and a large perimembranous ventricular septal defect, and the second case had an associated large patent ductus arteriosus. A bridge-type defect created two equal-sized openings in the mitral valve in case 1. In case 2, a small accessary opening was located in the posteromedial leaflet of the mitral valve. Double-orifice mitral valve is a rare anomaly associated with coarctation of the aorta, ventricular septal defect, and patent ductus arteriosus. The morphology of a double-orifice mitral valve can be clearly delineated by 2-D echocardiography.
