A persistent left superior vena cava (PLSVC) is the most common congenital anomaly of the thoracic venous return. During atrial septal defect repair, a pulmonary artery (PA) catheter was placed via the left internal jugular vein. Although placement of the PA catheter in the main PA was confirmed by transesophageal echocardiography, the central venous pressure (CVP) waveform was abnormal. Intraoperatively, the PA catheter was seen exiting the coronary sinus with the CVP port within the coronary sinus. The diagnosis of PLSVC is discussed and the differential diagnosis of the abnormal "ventricular" pattern of the CVP waveform is reviewed.
永存左上腔静脉（PLSVC）是最常见的胸段静脉回流先天性异常。在房间隔缺损修复期间，经左颈内静脉放置了肺动脉（PA）导管。尽管经食管超声心动图证实PA导管已置于主肺动脉内，但中心静脉压（CVP）波形异常。术中可见PA导管从冠状窦穿出，CVP端口位于冠状窦内。本文讨论了PLSVC的诊断，并回顾了CVP波形异常“心室”模式的鉴别诊断。
