瓣膜置换同期双极射频消融治疗心房颤动的早期疗效分析

Analysis of the Early Efficacy of Valve Replacement and Concomitant Bipolar Radiofrequency Ablation for Atrial Fibrillation

目的分析瓣膜置换同期双极射频消融治疗心房颤动的早期疗效。方法随机抽取同时期接收的心脏瓣膜疾病合并心房颤动患者122例为研究对象。瓣膜置换同期进行双极射频消融治疗心房颤动的患者为观察组,瓣膜置换且未进行双极射频消融治疗心房颤动的患者为对照组。观察2组患者术后的机械通气时间、重症监护治疗病房(ICU)停留时间、恶性心律失常率、左心室射血分数(LVEF)及左心室舒张末期内径(LVDd)指标,根据复查心电图及心脏彩色多普勒超声心动图分析临床治疗效果。结果在机械通气在时间、ICU停留时间、恶性心律失常率、LVEF以及近期疗效方面,观察组显著优于对照组,差别具有统计学意义(P<0.05)。2组LVDd指标比较,差别无统计学意义(P>0.05)。结论瓣膜置换同期双极射频消融治疗心房颤动的早期疗效显著,值得临床推广应用。

Objective To analyze the early efficacy of bipolar radiofrequency ablation procedure for atrial fibrillation during the heart valve replacement. Methods Clinical data of 122 patients with heart valve disease and atrial fibrillation(AF)in our hospital were randomly selected as research subjects. Valve replacement and concomitant bipolar radiofrequency ablation was performed for a observation group(n=70)while only the valve replacement was performed for a control group(n=52). Both groups were observed for the duration of mechanical ventilation,ICU stay time,the rate of malignant arrhythmia,LVEF and LVDd index. The clinical efficacy was evaluated according to the electrocardiogram and echocardiogram after the opration. Results On the mechanical ventilation time,ICU stay time,the rate of malignant arrhythmia,as well as LVEF,the observation group was significantly better than the control group,and the difference was statistically significant(P<0.05). LVDd index difference between the two groups was not statistically significant. Conclusion The valve replacement and concomitant bipolar radiofrequency ablation procedure for atrial fibrillation with early efficacy significantly,can be widely applied.
