导管射频消融治疗房颤40例临床分析

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O”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％，3mo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．

Clinical analysis on radiofrequency catheter ablation in 40 patients with atrial fibrillation

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 A...
