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.
报告了两例双孔二尖瓣病例。第一例与主动脉缩窄和巨大的膜周部室间隔缺损相关，第二例伴有巨大的动脉导管未闭。在第一例中，桥型缺损在二尖瓣上形成了两个大小相等的开口。在第二例中，一个小的副开口位于二尖瓣后内侧叶。双孔二尖瓣是一种与主动脉缩窄、室间隔缺损和动脉导管未闭相关的罕见畸形。二维超声心动图可清晰显示双孔二尖瓣的形态。
