A persistent left superior vena cava (LSVC) draining through a dilated coronary sinus into the right atrium is a relatively common congenital cardiovascular anomaly. It is readily identified by cardiovascular magnetic resonance (CMR). However, a LSVC draining into the left atrium (LA) and associated with unroofing of the coronary sinus, with resulting interatrial communication, is rare and may have important clinical consequences. As with any large atrial septal defect, it can be associated with a higher than expected incidence of pulmonary arterial hypertension, systemic embolization, and brain abscesses. In this report, we present a case of a completely unroofed coronary sinus with a persistent LSVC draining directly into the LA and illustrate the role of CMR in the diagnosis and evaluation of such anomalies.
一条持续存在的左上腔静脉（LSVC）通过扩张的冠状窦引流至右心房是一种相对常见的先天性心血管异常。它很容易通过心血管磁共振（CMR）识别出来。然而，一条LSVC引流至左心房（LA）并伴有冠状窦顶部缺如，从而导致心房间交通的情况则较为罕见，且可能具有重要的临床后果。与任何大型房间隔缺损一样，它可能与高于预期的肺动脉高压、体循环栓塞和脑脓肿发生率相关。在本报告中，我们展示了一例冠状窦完全顶部缺如且伴有持续存在的LSVC直接引流至LA的病例，并阐述了CMR在诊断和评估此类异常中的作用。
