摘要
目的：探讨采用环肺静脉前庭电隔离（CPVA）治疗房间隔缺损（ASD）合并心房颤动的方法学及临床疗效。方法：8例ASD合并持续性房颤患者，其中男5例，女3例，平均年龄（48．7±17．6）岁，2例为拟行ASD修补或封堵术患者，6例为ASD修补术后患者，均采用三维电解剖标测系统（CARTO）指导下环肺静脉消融，消融终点为肺静脉电隔离。结果：8例患者均实现术中消融终点，1例ASD患者CP—VA术后行封堵术，1例患者术后行外科手术；1例ASD修补术后患者CPVA术后1个月房颤复发，再次采用CARTO指导下环同侧肺静脉的线性消融。手术时间为145～235min，平均（180±30）min；X线曝光时间为18～32min，平均（25±5）min。术中及术后未发生任何操作相关并发症，随访1～6个月房颤无复发。结论：CPVA对ASD合并房颤患者有较好的临床疗效，对ASD合并房颤患者可首先考虑CPVA治疗，然后再进行介入封堵。
Objective To investigate methodology and clinical efficacy of atrial fibrillation （AF） by circumferential pulmonary vein antrum isolation （CPVA） in patients with atrial septal defect （ASD）. Methods：8 cases, 5 males and 3 female, with mean age （48.7± 17.6） years, were ASD with persistent AF. Among them, 2 cases were planned to perform ASD operations of repair or closure, and 6 cases were post-repair patients. CPVA guided by CARTO XP in pulmonary veins was done in these 8 patients. Results CPVA end point was reached in 8 patients during ablation. The closure was performed after CPVA in 1 patient, and 1 case received surgical operation. AF reoccurred in 1 case in one month after CPVA. CPVA guided by CARTO XP in pulmonary veins of was performed again. The operation time was （180±30）min and X-ray exposure time was （25 ±5）min. No complications resulting from procedures ap- peared pre and post operations. No AF reoccurred during 1~6 months＇ follow-up. Conclusion..CPVA has significant effect on AF in ASD patients. CPVA should be first considered to deal with AF in patients with ASD, and then the closure continues.
