We describe a 66-year-old man who required an operation for severe mitral regurgitation associated with a double-orifice mitral valve. Real-time 3-dimensional transesophageal echocardiography clearly demonstrated a double-orifice mitral valve with a central fibrous bridge. A flail posterior leaflet was observed on the anterolateral mitral valve orifice. Mitral valve repair using P1 triangular resection, anterolateral commissure plication, and ring annuloplasty with Duran band (Medtronic, Minneapolis, MN) was successfully performed. Postoperative real-time 3-dimensional transesophageal echocardiography demonstrated a double-orifice mitral valve without regurgitation or stenosis.
我们描述了一位 66 岁男性，因严重二尖瓣反流合并二尖瓣双孔畸形需要手术治疗。实时三维经食管超声心动图清晰显示中央纤维性桥连接的二尖瓣双孔畸形。前外侧二尖瓣口可见后叶连枷。采用 P1 三角形切除、前外侧交界折叠和 Duran 带（美敦力，明尼苏达州明尼阿波利斯）环瓣成形术成功进行了二尖瓣修复。术后实时三维经食管超声心动图显示二尖瓣双孔畸形无反流或狭窄。
