对1993～2003年10年间开展射频消融治疗的1108例快速性心律失常进行总结,统计其成功率、复发率、并发症发生率,并比较射频消融开始时与近期5年的有关指标。结果:①各种心律失常治疗总成功率为96.7%,其中房室折返性心动过速(AVRT)98.3%、房室结折返性心动过速(AVNRT)97.5%;总复发率3.7%,其中AVRT3.1%、AVNRT2.6%;总并发症发生率0.99%;②近期5年与开始时5年相比,每例患者的手术时间明显缩短(1.1±0.6hvs4.2±0.8h,P<0.001),X线照射时间减少(20.1±7.1minvs40.3±10.3min,P<0.001),复发率降低(1.6%vs6.8%,P<0.001),并发症发生率降低(0.6%vs1.6%,P<0.001),成功率进一步提高(98.40%vs93.20%,P<0.05)。结论:①射频消融根治快速性心律失常安全、有效、复发率低、并发症少;②随着治疗病例数增多,技术水平明显提高。
A total of 1108 patients with tachyarrhythmia who underwent radiofrequency catheter ablation in the past 10 years from 1993 to 2003 were summarized. The success rate, recurrence rate and complication rate were compared. The relevant indexes at the beginning of radiofrequency ablation and the recent five years were compared. Results: ① The total success rate of various arrhythmia treatment was 96.7%, including atrioventricular reentrant tachycardia (AVRT) 98.3%, atrioventricular nodal reentrant tachycardia (AVNRT) 97.5% and total recurrence rate 3.7% AVRT3.1% and AVNRT2.6%, respectively. The overall complication rate was 0.99%. Compared with the first five years, the operation time of each patient was significantly shortened (1.1 ± 0.6hvs4.2 ± 0.8h, P (P <0.001). The time of X-ray irradiation decreased (20.1 ± 7.1min vs. 40.3 ± 10.3min, P <0.001), and the recurrence rate decreased (1.6% vs 6.8%, P <0.001) .6%, P <0.001). The success rate was further improved (98.40% vs93.20%, P <0.05). Conclusion: Radiofrequency ablation is a safe and effective method for radical tachyarrhythmia, with low recurrence rate and few complications. With the increase of the number of cases treated, the technical level is significantly improved.
