Wolff-Parkinson-White (WPW) syndrome causes paroxysmal supraventricular tachycardia (PSVT) and catheter ablation is the most effective therapy method. We summarized a rare case of WPW syndrome. The patient suffered from WPW syndrome complicated with an atrial septal defect (ASD), persistent left superior vena cava, and absence of inferior vena cava. A hybrid operation was arranged to solve his problem. During the procedure, we did endocardial and epicardial mapping and ablation, respectively. Conduction of the accessory pathway could be temporarily obstructed, but recovered soon later. Considering it was a rare and interesting case worth recording and discussing, we share it with the public.

WPW综合征并发心血管畸形患者的混合射频消融

Wolff-Parkinson-White（WPW）综合征引起阵发性室上性心动过速（PSVT），导管消融是最有效的治疗方法。我们总结了WPW综合征的罕见情况。该患者患有WPW综合征，并伴有房间隔缺损（ASD），持续性左上腔静脉以及无下腔静脉。安排了一次混合行动来解决他的问题。在此过程中，我们分别进行了心内膜和心外膜定位和消融。辅助通路的传导可能暂时受阻，但不久后就恢复了。考虑到这是一个罕见的有趣案例，值得记录和讨论，我们与公众分享。
