预激综合征伴房颤射频消融治疗的探讨

The explore of the method of radiofrequency ablation on atrial fibrillationin patients with preexcitation syndrome

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 recurrence rate of atrial fibrillation after the two methods of radiofrequency ablation of atrioventricular accessory pathway and radiofrequency ablation of atrioventricular accessory pathway with circle pulmonary vein isolation in preexcitation syndrome patients with atrial fibrillation. Methods This study included 58 cases with preexcitation syndrome patients with atrial fibrillation, they were randomly divided into two groups： one done with radiofrequency ablation of atrioventricular accessory pathway （referred to the simple group） involved 22 cases and the other dealed with radiofrequency ablation of atrioventricular accessory pathway with circle pulmonary vein isolation （referred to the jiont group） included 36 patients. Patients in the two groups were followed up to observe whether atrial fibrillation reocurred or not. Results The longest follow-up was 42 months and the shortest follow-up was 3 months. There were no case reocurred atrial fibrillation in the two groups during the follow-up periods（p0.05）. Conclusions The successful radiofrequency ablation of ablation of atrioventricular accessory pathway can singnificantly reduce the recurrence of atrial fibrillation, and the radiofrequency ablation of atrioventricular accessory pathway with circle pulmonary vein isolation is not better than the radiofrequency ablation of atrioventricular accessory pathway in patients with preexcitation syndrome.
