目的观察房室旁路射频消融术与房室旁路射频消融联合环肺静脉电隔离术两种消融方法治疗预激综合征伴心房颤动患者的疗效。方法本研究纳入58例预激伴房颤患者,随机分为两组,一组为单纯行房室旁路射频消融术(单纯组)36例,另一组为房室旁路射频消融术联合环肺静脉电隔离术(联合组)22例,术后随访两组患者房颤的复发情况。结果最长随访42个月,最短随访3个月,两组随访期间均无一例患者发生房颤(p>0.05),差异无统计学意义。结论在预激伴房颤患者中,房室旁路射频消融联合环肺静脉电隔离术不优于单纯房室旁路消融术;房室旁路消融术可减少预激伴房颤患者的房颤再发率。
Objective To observe the curative effect of two kinds of ablation methods of atrioventricular bypass radiofrequency ablation and atrioventricular bypass radiofrequency ablation combined with circumferential pulmonary vein isolation in the treatment of WPW syndrome with atrial fibrillation. Methods Fifty-eight patients with preexcited atrial fibrillation were randomly divided into two groups. One group consisted of 36 patients with simple atrioventricular shunt radiofrequency ablation (simple group), and the other group received combined atrioventricular shunt radiofrequency ablation Central pulmonary vein isolation (combined group) 22 cases, two groups were followed up the recurrence of atrial fibrillation. Results The longest follow-up was 42 months and the shortest follow-up period was 3 months. No one had atrial fibrillation during the follow-up period (p> 0.05). There was no significant difference between the two groups. Conclusions In patients with preexcited AF, atrioventricular bypass radiofrequency ablation combined with circumferential pulmonary vein isolation is not superior to simple atrioventricular bypass ablation. Atrioventricular bypass ablation can reduce atrial fibrillation in patients with preexcited atrial fibrillation Recurrence rate.
