Cor triatriatum dexter (CTD) is a rare congenital cardiac anomaly in which a membranous structure divides the right atrium (RA) into two chambers. Persistence of the right valve of the sinus venosus, which usually regresses as a part of normal embryological development, is responsible for membranous partition. There is a high incidence of right-sided congenital abnormalities of the heart associated with this condition. Clinical manifestations vary depending on the degree of partitioning or septation of the RA. We present a case of CTD discovered as an incidental finding during transthoracic echocardiography and further discuss the role of two-dimensional echocardiography as a noninvasive diagnostic tool.
右心房三房心（CTD）是一种罕见的先天性心脏异常，其中一个膜性结构将右心房（RA）分为两个腔室。静脉窦右瓣通常作为正常胚胎发育的一部分而退化，其持续存在是膜性分隔的原因。这种情况与右侧先天性心脏异常的发生率较高有关。临床表现因右心房分隔或间隔的程度而异。我们报告一例在经胸超声心动图检查时偶然发现的CTD病例，并进一步讨论二维超声心动图作为一种无创诊断工具的作用。
