目的:总结分析经导管射频消融(RFCA)治疗快速型心律失常的效果及并发症,以进一步指导临床治疗。方法:对我院行RFCA治疗快速型心律失常1 268例的临床资料进行回顾性分析。结果:本组1 268例中,房室折返性心动过速682例,房室结折返性心动过速453例,室性心动过速和室性期前收缩62例,房性心动过速18例,心房扑动17例,心房颤动36例。RFCA总成功率为97.5%,并发症发生率为0.79%。术中出现一过性房室传导阻滞10例,其中2例因并发永久性Ⅲ度房室传导阻滞予安置永久性心脏起搏器,发生心包填塞、气胸、下肢动脉栓塞及深静脉血栓形成各1例;术后发生假性动脉瘤1例。均经相应处理后治愈,未出现瓣膜损伤、感染等并发症,无与RFCA相关的死亡病例。结论:RFCA治疗快速型心律失常具有安全、有效、成功率高、并发症发生率低等优点,如术前认真准备、术中仔细操作、术后细心观察可提高手术的成功率,减少并发症的发生。
OBJECTIVE: To summarize and analyze the effect and complications of transcatheter radio-frequency ablation (RFCA) in the treatment of tachyarrhythmia, so as to further guide the clinical treatment. Methods: The clinical data of 1 268 cases of tachyarrhythmia treated by RFCA in our hospital were analyzed retrospectively. Results: In this group of 1 268 cases, 682 cases of atrioventricular reentrant tachycardia, atrioventricular nodal reentrant tachycardia 453 cases, ventricular tachycardia and ventricular contraction in 62 cases, atrial tachycardia in 18 cases , Atrial flutter in 17 cases, atrial fibrillation in 36 cases. RFCA assembly rate was 97.5%, complication rate was 0.79%. Surgery occurred in 10 cases of atrioventricular block, including 2 cases of permanent Ⅲ degree atrioventricular block due to permanent permanent placement of pacemaker, the occurrence of pericardial tamponade, pneumothorax, lower extremity arterial embolism and deep venous thrombosis Formed in 1 case; pseudoaneurysm occurred in 1 case. All of them were cured after the corresponding treatment. There were no complications such as valve injury and infection, and no deaths related to RFCA. Conclusion: RFCA has the advantages of safe, effective, high success rate and low complication rate. For example, careful preparation before operation, careful operation during operation and careful observation after operation can improve the success rate of operation and reduce the complications happened.
