特发性室性心律失常射频消融术治疗的疗效及安全性分析

摘要

目的：通过对本院经射频消融术治疗的特发性室性心律失常患者资料进行回顾性分析及随访,从而评估我院特发性室性心律失常经射频消融术治疗的疗效与安全性。方法选取自2008年1月至2014年3月在本院接受射频消融术治疗的特发性室性心律失常患者63例,进行定期门诊或电话随访,复查 Holter 观察射频消融术后室性心律失常发作情况,心动超声比较左室舒张末期内径大小及射血分数变化。结果射频消融术治疗特发性室性心律失常的即刻成功率为89.29%,远期成功率为82.14%；射频消融术前术后心动超声示左室射血分数及左室舒末内径无明显改善(P >0.05)；射频消融术后 Holter 示室性早搏负荷较术前明显减少(P <0.05)；1例患者射频消融术后合并主动脉佛氏窦瘤破裂,1例出现股动脉穿刺处血肿形成。结论射频消融术治疗特发性室性心律失常是安全而有效的。%Objective To assess the effectiveness and safety of radiofrequency catheter ablation for idiopathic ventricular arrhythmia in patients with idiopathic ventricular arrhythmia after radiofrequency catheter ablation treated in the First Affiliated Hospital of Xi’an Jiaotong University based on the follow-up and retrospective analysis.Methods We retrospectively analyzed the clinical data of 63 patients with idiopathic ventricular arrhythmia who underwent radiofrequency catheter ablation during January 2008 and March 2014 in the First Affiliated Hospital of Xi’an Jiaotong University.In the follow-up,Holter moniterings were reviewed to evaluate ventricular arrhythmia and echocardiography to assess the ejection fractions and left ventricular end-diastolic diameters.Results The immediate success rate of catheter ablation for the treatment of idiopathic ventricular arrhythmia was 89.29% and the long-term success was 82.14%.The ejection fractions and left ventricular end-diastolic diameters were not obviously improved after radiofrequency ablation (P > 0.05 ). The ventricular premature contractions were significantly reduced after radiofrequency ablation (P <0.05).In postoperative care, one case was found with ruptured sinus valsalva tumor and another patient was found with the complication of hematoma in femoral artery puncture.Conclusion Radiofrequency ablation for idiopathic ventricular arrhythmia is safe and effective.
