摘　　要：目的评价环肺静脉电隔离加心房线性消融治疗持续性心房颤动（房颤）的有效性和安全性。方法入选481例经导管射频消融治疗房颤的多中心临床注册研究（AFCT研究）的持续性房颤患者，分单一环肺静脉电隔离组（CPVI组，205例）和环肺静脉电隔离加心房线性消融组（CPVI＋LL组，276例）。分析比较两组手术时间、X线曝光时间、消融时间、并发症发生率以及术后3、6和12个月的成功率。结果CPVI＋LL组手术时间[（239．0±56．6）min对（159．3±51．5）min，P〈0．01]和消融时间[（94．8±22．5）min对（60．2±16．6）min，P〈0．01]明显长于CPVI组，但两组X线曝光时间差异无统计学意义（（47．5±18．2）min对（52．4±21．6）min，P〉0．05]。两组围术期并发症发生率差异无统计学意义（0．72％对0．98％，P〉0．05）。两组术后3和6个月成功率无明显差异，但CPVI＋LL组术后12个月的成功率明显高于CPVI组（74．2％对62．1％，P〈0．05）。结论CPVI基础上增加心房辅助径线消融对持续性房颤是必要的，可增加持续性房颤中长期成功率。Objective To investigate the safety and efficacy of circumferential pulmonary vein isola- tion （CPVI） plus linear lesion in patients with persistent atrial fibrillation （AF）. Methods This study includ- ed 481 patients registered in the Atrial Fibrillation Clinical Trial （AFCT） in China. All patients had persistent AF and received CPVI （ CPVI group, n = 205 ） or CPVI plus linear lesion （ CPVI＋LL group, n = 276 ）. The total time of the procedure ,time of fluoroscopy ,time of radiofrequency applications, complications incidence and suc- cess rate at 3,6,12-month follow-up were compared. Results The total time of the procedure and time of ra- diofrequency applications in CPVI＋LL group were significantly longer than that in CPVI group [ （239.0±56. 6） min vs （ 159. 3 ±51.5 ） min, P〈0. 01 ; （ 94. 8 ±22. 5 ） min vs （ 60. 2± 16. 6 ） rain, P〈0.01 ], but the time of fluoros- copy had no significant difference between two groups [ （ 47. 5 ± 18.2 ） min vs （ 52. 4± 21.6 ） min, P 〉 0. 051. In addition,there was no significant difference in the complications incidence between two groups （0. 72% vs 0. 98% ,P〉O. 05）. The success rate at 3-month and 6-month follow-up had no significant difference between two groups ,but CPVI＋LL group achieved a significant higher success rate than CPVI group at 12-month follow- up （74. 2% vs 62. 1% ,P〈0. 05 ）. Conclusion For persistent AF, CPVI plus linear lesion is necessary, which can increase the long-term success rate.
