射频消融术治疗特发性室性心律失常的临床研究

Clinical study on radiofrequency ablation in the treatment of idiopathic ventricular arrhythmia

目的探讨特发性室性心律失常(IVA)患者行射频消融术治疗的临床疗效。方法回顾性分析该院68例射频消融术治疗IVA患者术中电生理特点及射频消融结果。结果 68例患者中,61.8%(42/68)的特发性室性心律失常患者为右心室来源,38.2%(26/68)为左心室来源。右心室来源的患者以流出道最多见,射频消融术的手术即时成功率为90.5%(38/42),手术后1月内复发率为2.6%(1/38);左心室来源的患者以流入道多见,射频消融术的手术即时成功率为92.3%(24/26),手术后1月内复发率为4.2%(1/24)。68例患者出现手术并发症2例(2.9%),均为心包填塞,经治疗后好转。所有患者均无房室传导阻滞、瓣膜损伤和死亡等其他并发症。结论射频消融术是特发性室性心动过速简捷、安全、有效的首选治疗方法。

Objective To investigate the clinical efficacy of radiofrequency ablation for idiopathic ventricular arrhythmia（IVA）. Methods Perioperative eleetrophysiological characteristics and radiofrequency ablation results of 68 IVA patients were analyzed retrospectively. Results Of all 68 IVA patients, 42 originated from fight ventricle, accounting 61.8%, and 26 from left ventricle, accounting 38.2%. Right ventricle outflow tract was the most common origin for patients with fight ventricle originated IVA whose instant success rate was 90.5% （38/42）with a one-month recurrence rate of 2.6% （1/38）. Left ventricle inflow tract was the most common origin for patients with left ventricle originated IVA whose instant success rate was 92.3% （ 24/26 ） with a one-month recurrence rate of 4.2% （ 1/24 ）. There were 2 cases of pericardial tamponade during ablations which recovered after treatment. No A-V block, valve injury, or death happened. Conclusion Radiofrequency ablation is a quick, safe, and effective preferred method for idiopathic ventricular tachycardia.
