A patient with rheumatic mitral valve disease and persistently elevated jugular venous pressure (JVP) is described. Angiography revealed a valve-like structure in the superior vena cava (SVC) at the site where a pressure gradient was recorded. At operation, this previously unreported anomaly proved to have been caused by aneurysmal dilatation of the left atrium which exerted traction on the pericardial insertion to the SVC. Disinsertion of the pericardial attachment to the vena cava at the time of mitral valve replacement released the compression. Postoperatively, the JVP became normal.
本文描述了一名患有风湿性二尖瓣疾病且颈静脉压（JVP）持续升高的患者。血管造影显示，在上腔静脉（SVC）记录到压力梯度的部位存在一个瓣膜样结构。手术时发现，这一此前未报告过的异常情况是由左心房的动脉瘤样扩张引起的，该扩张对心包与上腔静脉的连接处产生了牵拉。二尖瓣置换手术时，心包与上腔静脉连接处的分离解除了压迫。术后，颈静脉压恢复正常。
