Coronary sinus (CS) anomalies such as diverticulum, persistent left superior vena cava or CS ostium dilatation are predominantly found in patients with accessory pathway-related tachycardias. Diverticulum of the proximal CS found in 7-11% of patients with postero-septal or left posterior manifests accessory pathways. We reported a 28 year old gentleman with manifested postero-septal accessory pathway, who underwent repeat electrophysiological study (EPS) and radiofrequency ablation for previously failed ablation. Huge CS diverticulum was identified by angiography as a reason for resistant accessory pathway. Successful RF ablation was achieved at the neck of the diverticulum without complications. Other associated anomalies were ruled out by cardiac computerized tomography (CT) and trans-esophageal echocardiography.
冠状窦（CS）异常，如憩室、永存左上腔静脉或冠状窦口扩张，主要见于与旁路相关的心动过速患者。在7%至11%的后间隔或左后旁路患者中发现近端冠状窦憩室。我们报告了一名28岁患有后间隔旁路的男性，他因之前消融失败而接受了重复电生理检查（EPS）和射频消融。血管造影发现巨大的冠状窦憩室是旁路难以消融的原因。在憩室颈部成功进行了射频消融，无并发症。心脏计算机断层扫描（CT）和经食管超声心动图排除了其他相关异常。
