目的:回顾性分析射频消融(RFCA)治疗高龄患者房室结折返性心动过速(AVNRT)的有效性和安全性。方法:2005年1月至2008年1月阵发性房室结折返性心动过速的高龄患者21例采用射频消融治疗。结果:21例患者首次消融成功20例,消融成功率95.2%,1例术中失败患者拒绝二次手术,术后共随访9～36个月,均未复发,复发率0%。并发症发生率9.5%,1例为肺气肿患者发生少量气胸,1例放电时出现Ⅰ度房室传导阻滞(PR间期0.28s),无死亡病例。结论:射频消融治疗高龄患者房室结折返性心动过速是有效的、安全的。
Objective: To retrospectively analyze the effectiveness and safety of radiofrequency ablation (RFCA) in treatment of atrioventricular nodal reentrant tachycardia (AVNRT) in elderly patients. Methods: From January 2005 to January 2008, 21 patients with paroxysmal atrioventricular nodal reentrant tachycardia were treated with radiofrequency ablation. Results: Twenty patients were successfully ablated for the first time in 20 cases, and the success rate of ablation was 95.2%. One patient with intraoperative failure refused the second operation and all patients were followed up for 9-36 months. No recurrence was found and the recurrence rate was 0%. The incidence of complications was 9.5%. One patient had emphysema with a small amount of pneumothorax. One patient had Ⅰ degree atrioventricular block (PR interval 0.28s) without any death. Conclusion: Radiofrequency catheter ablation in elderly patients with atrioventricular nodal reentrant tachycardia is effective and safe.
