摘要
目的:探讨导管射频消融治疗房颤的疗效、安全性及复发的相关因素.方法:40例房颤患者,阵发性房颤35例,慢性房颤5例.3例行节段性肺静脉电隔离术,16例行Carto三维标测系统指导下的环肺静脉消融及(或)左房、右房线性消融,21例采用EnSite三维标测系统指导下的"7或0"型左房线性消融和(或)右房峡部消融.总结房颤消融的成功率和复发率、并发症发生情况.结果:射频消融的即刻成功率100%,3 mo后判断手术成功率,所有患者一次手术成功率87.5%(35/40),5例再发房扑或房速的患者中4例再次行射频消融术,两次术后仍有3例复发房扑,两次手术成功率90%(36/40),3例两次术后再发房扑的患者中仅1例患者行第三次射频消融术.阵发性房颤一次手术成功率97.1%(34/35),并发症发生率2.5%(1/40),无严重并发症发生.术后复发者均为大折返房扑或房速,复发与患者发病时间长、持续性房颤、左心房大、患者年龄大、合并高血压病等有关.结论:房颤射频消融治疗房颤效果较好且安全.
Abstract
AIM: To investigate the efficacy and safety of catheter ablation of atrial fibrillation(AF). METHODS: Forty cases were diagnosed AF, 35 cases were paroxysmal and 5 cases were chronic. Segmental pulmonary vein isolation were performed in 3 cases, circumflex pulmonary vein isolation by Carto in 16 cases and by EnSite in 21 cases. Efficacy and safety were evaluated. RESULTS: The primary successful rate was 100%, sinus rhythm was sustained in 83.3% patients after three months. The successful rate was 97.1% in paroxysmal AF. There was no severe complications. CONCLUSION: Radiofrequency ablation of atrial fibrillation is effective and safe.
