A case of an acquired left ventricular-right atrial communication complicating Omnicarbon replacement of a severe calcified mitral valve in the area of the posteromedial commissure is reported. The intricate relationships of the membranous atrioventricular septum to the mitral valve and the tricuspid valve predispose to the creation of an iatrogenic left ventricular-right atrial fistula when aggressive debridement of extensive valvular calcification is performed. Emphasis is placed on the diagnosis, and immediate surgical repair is advocated as soon as this complication is discovered.
本文报告1例因后内侧连合处严重钙化二尖瓣行全碳二尖瓣置换术后出现获得性左心室-右心房交通的病例。当对广泛的瓣膜钙化进行积极清创时，膜性房室间隔与二尖瓣和三尖瓣的复杂关系易导致医源性左心室-右心房瘘的形成。重点在于诊断，一旦发现此并发症，主张立即进行手术修复。
