Thirteen patients with Wolff-Parkinson-White syndrome were ablated with radiofrequency current. The thirteen septal atrioventricular accessory pathways in these patients included 4 right anteroseptal, 4 right posteroseptal and 5 left posteroseptal. For patients with right anteroseptal and posteroseptal accessory pathways, a large-tip ablation catheter was advanced via right femoral vein to an area just above the His bundle and around the coronary sinus ostium. For patients with left posteroseptal accessory pathways. An ablation catheter was placed at the left ventricular side of mitral annulus. All of the accessory pathways were abolished successfully. The average current applications was 14 and mean accumulated energy was 18,900 joules. The mean procedure period is 2.3 hours. There were no severe complications and there was no recurrence after 6 months of follow-up. It is shown that radiofrequency current ablation of septal accessory pathways in patients with Wolff-Parkinson-White syndrome is a safe and effective modality of treatment.
13例预激综合征患者接受了射频电流消融治疗。这些患者的13条间隔房室旁道包括4条右前间隔旁道、4条右后间隔旁道和5条左后间隔旁道。对于右前间隔和后间隔旁道患者，将大头消融导管经右股静脉推进至希氏束上方及冠状窦口周围区域。对于左后间隔旁道患者，将消融导管置于二尖瓣环的左心室侧。所有旁道均成功阻断。平均放电次数为14次，平均累积能量为18900焦耳。平均手术时间为2.3小时。无严重并发症，随访6个月无复发。结果表明，射频电流消融预激综合征患者的间隔旁道是一种安全有效的治疗方法。
