A 71 year old asymptomatic woman came for an echocardiogram because of a left bundle branch block. A much dilated coronary sinus (CS) with an entering large vessel was found along with a mild left ventricular systolic dysfunction. Cardiac Magnetic Resonance (CMR) showed a persistent left superior vena cava (PLSVC), and an absent right superior vena cava (ARSVC). PLSVC drained into the dilated CS. No other cardiac abnormalities were found. Any late Gadolinium enhancement was also not seen. PLSVC and ARSVC are associated with sinus node and conduction tissue maldevelopment and atrial arrhythmias, and thus clinical follow up is indicated.
CMR is a useful addition to echocardiogram to search for further cardiac abnormalities, and outline the anatomy with precision in doubtful cases.
一名71岁无症状女性因左束支传导阻滞前来进行超声心动图检查。发现冠状窦（CS）明显扩张且有一大血管汇入，同时伴有轻度左心室收缩功能障碍。心脏磁共振成像（CMR）显示存在永存左上腔静脉（PLSVC），而右上腔静脉缺如（ARSVC）。PLSVC汇入扩张的CS。未发现其他心脏异常。也未观察到延迟钆增强。PLSVC和ARSVC与窦房结及传导组织发育异常和房性心律失常有关，因此需要进行临床随访。
CMR是对超声心动图的有益补充，可用于进一步查找心脏异常，并在疑难病例中精确勾勒解剖结构。
