射频消融术治疗阵发性室上性心动过速382例临床分析

目的评估经导管射频消融术(RFCA)治疗阵发性室上性心动过速的临床疗效。方法对心内科近两年382例伴不同阵发性室上性心动过速的患者采用射频消融治疗,对治疗结果进行回顾性分析,比较左侧旁道、右侧旁道及房室结双径路伴阵发性室上性心动过速患者术后成功率、复发率及并发症发生率等临床数据的差异。结果房室折返性心动过速患者174例,其中左侧旁道113例,右侧旁道61例;房室结折返性心动过速208例。射频消融总成功率为97.4%,其中房室结双径路和左侧房室旁道介导的阵发性室上速射频消融成功率达98.4%。射频消融术后总复发率为2.6%,并发症发生率为1.8%。结论射频消融治疗快速室上性心律失常安全、有效,成功率高,并发症发生率低。右侧旁道消融复发率高于左侧旁道及双径路。

Clinical analysis of radiofrequency catheter ablation on paroxysmal supraventricular tachycardia

Objective This study was to analyze the outcomes of patients with paroxysmal supravetricular taehy- cardia after therapeutic radiofrequency catheter ablation for further clinical operating works. Methods Clinical data of 382 patients with different supravetricular taehyeardia received radiofrequency ablationtherapy were retrospectively analyzed. Results There were 174 patients with atrioventricular reentrant tachycardia. Among them, there were 113 cases with left accessory pathways, 61 cases with right accessory pathways. There were 208 patients with atrioventricular nodal re- entrant tachycardia. The overallsuccess rate was 97.4%, in which radiofrequency catheter ablation of paroxysmal su- praventricular taehycardia mediated by dual atrioventricular nodal and left accessory pathway had a higher success rate （98.4%）. The overall recurrence rate was 2.6% and the incidence of complications was 1.8~ after radiofrequency cath- eter ablation. Conclusion Radiofrequency catheter ablation is an effective and safe therapeutic method with high successful rate, low incidence of complications for patients with paroxysmal supravetricular tachycardia. The patients with right accessory pathway had a higher recurrence rate.
