全军射频导管消融治疗快速心律失常资料总汇

目的汇总分析全军射频导管消融(radiofrequency catheter ablation,RFCA)治疗快速心律失常资料,了解此项工作的现状与不足。方法由全军心血管内科专业委员会组织进行RFCA治疗快速心律失常资料的注册登记和统计分析。两次注册时间分别为：1993年1月1日至2000年12月31日和2001年1月1日至2002年12月31日。结果(1)两次注册共收到全军42家医院共14,599例登记资料,总成功率为96．5％(14092／14599),复发率为2．8％(400／14092),并发症发生率为0．5％(72／14599)。(2)各类心律失常中房室折返性心动过速(AVRT)为8344例(57．2％),房室结折返性心动过速(AVNRT)4822例(33％)。(3)AVNRT及AVRT始终保持较高水平的成功率,频发室性早搏成功率显提高。心房颤动(AF)和非特发性室性心动过速(nod—IVT)复发率仍较高,分别为27％和21．3％。并发症共发生72例,其中最多的为完全性房室传导阻滞23例(31．9％)和心包填塞19例(26．4％)。结论全军RFCA治疗快速性心律失常工作发展迅速。加强培训,努力提高个人的技术水平,仍是将来减少复发率和控制并发症的主要途径。

The survey on radiofrequency catheter ablation in Chinese military hospitals

Objective To analyze the cumulative data of radiofrequency catheter ablation (RFCA) in the treatment of tachyarrhythmias in Chinese military hospitals. Methods Chinese PLA Cardiology Association sponsored the registration and statistical analysis. RFCA results were registered from January 1, 1993 to December 30, 2000 and from January 1, 2001 to December 30, 2003 respectively. Results (1) A total of 14 599 patients from 42 hospitals underwent RFCA, RFCA was successful in 14 092 of 14 599 (success rate 96.5%) with a complication rate 0.5% (72/14599) and recurrence rate 2.8% (400/ 14 599). (2) The number of patients with accessory pathway (AVRT) and AV nodal reentrant tachycardia (AVNRT) were 8344 and 4822 respectively. (3) High success rate was maintained in AVNRT and AVRT ablation, success rate was significantly improved in the treatment of PVCs. Atrial fibrillation and non-idiopathic ventricular tachycardia ablation presented high recurrence rate with 27% and 21.3% respectively. The total number of complication was 72 cases, in which complete AV block and cardiac tamponade accounted for 31.9% (23/72) and 26.4% (19/72) respectively. Conclusion RFCA for the treatment of tachyarrhythmias was rapidly developed in Chinese military hospitals. Improving the level of technical training and practice will play an important role in reducing complication and recurrence rate.
