We herein present a 5-month-old boy with an infravalvular-type left ventricular-right atrial communication without an abnormal tricuspid valve leaflet. The thick chorda of the anterior tricuspid leaflet was inserted into the upper edge of the ventricular septal defect which was placed just under the commissure. The jet from the septal defect pushed this thick chorda and opened the commissure, which thus caused the abnormal pathway from the left ventricle to the right atrium. This mechanism of left ventricular-right atrial communication has not yet been reported elsewhere.
我们在此报告一名5个月大的男孩，其存在瓣膜下型左心室-右心房交通，且三尖瓣叶无异常。三尖瓣前叶的粗大腱索插入室间隔缺损的上缘，该缺损恰好位于瓣叶联合处下方。室间隔缺损处的血流喷射推动这根粗大腱索并打开瓣叶联合处，从而导致了从左心室到右心房的异常通路。这种左心室-右心房交通的机制在其他地方尚未见报道。
