Cor triatriatum dexter (CTD) is an extremely rare congenital condition arising from the persistence of the right valve of the sinus venosus. It divides the right atrium (RA) into 2 separate chambers. We report a case of a 50-year-old man who had an incidental finding of CTD on transesophageal echocardiogram. An incomplete membrane of the RA was seen, and three-dimensional echocardiogram delineated the structure clearly as a triangular sail-like structure with multiple orifices and a fenestration.
右三房心（CTD）是一种极为罕见的先天性疾病，由静脉窦右瓣持续存在引起。它将右心房（RA）分为两个独立的腔室。我们报告一例50岁男性，经食管超声心动图偶然发现患有CTD。可见右心房有一不完全隔膜，三维超声心动图将其清晰描绘为一个具有多个小孔和一个开窗的三角形帆状结构。
