Cor triatriatum is a congenital heart malformation that is characterised by the division of the left or right atrium into two separate chambers by a membrane or diaphragm. Reports among adults are scarce, as most cases are diagnosed during childhood. The risk of mortality is increased when cor triatriatum is complicated by pulmonary hypertension. This is a report of an 86-year-old woman with World Health Organization Group 2 pulmonary hypertension secondary to cor triatriatum, discovered during preoperative workup. Echocardiography showed a membrane dividing the left atrium into two. Doppler studies revealed a reversal of normal flow, similar to mitral stenosis. The right ventricle was dilated, with reduced long axis function.
三房心是一种先天性心脏畸形，其特征是左心房或右心房被膜或隔膜分隔成两个独立的腔室。成人中的报告很少，因为大多数病例在儿童期就被诊断出来。当三房心并发肺动脉高压时，死亡率会增加。这是一例 86 岁女性的报告，她患有世界卫生组织 2 级肺动脉高压，继发于三房心，在术前检查中发现。超声心动图显示有一个膜将左心房分隔成两部分。多普勒研究显示正常血流方向逆转，类似于二尖瓣狭窄。右心室扩张，长轴功能降低。
