房颤射频消融术对阵发性房颤患者心脏形态和功能的影响

Effect of Catheter Radiofrequency Ablation on Cardiac Morphology in Patients With Paroxysmal Atrial Fibrillation

目的探讨房颤射频消融术治疗阵发性房颤患者心脏形态和功能的影响,评价导管消融术治疗房颤的有效性和安全性。方法收集116例行导管射频消融术治疗的房颤患者的术前资料,治疗前及治疗后1、3、6个月分别经多普勒超声心动图测量左心房前后径(LAD),右心房前后径(RAD),左室射血分数(LVEF%)。术后随访6个月,监测房颤复发情况。结果所有患者经导管射频消融治疗后效果理想,随访6个月内房颤复发率低,左、右心房直径均明显缩小(P<0.05),EF值明显升高(P<0.05)。结论房颤射频消融术能显著缩小房颤患者左、右心房内径,改善心功能,是安全有效的房颤治疗方法。

Objective To detect the effect of radiofrequency catheter ablation（RFCA） on cardiac morphology in patients with paroxysmal atrial ifbrillation. Methods 116 patients with paroxysmal AF undergoing RFCA were studied. Left atrium （LA） diameter, right atrium （RA） diameter, left ventricular ejection fraction （LVEF） , were observed 1, 3 and 6 monthsafter RFCA and compared with before RFCA. The recurrence of atrial arrhythmias was observed 3 and 6 months after the procedure. Results During a follow-up of six months, the outcomes of RFCA were satisfying with decreased recurrence of AF. Compared with before RFCA, LAD and RAD decreased and LVEF increased significantly after RFCA（P〈0.05）. Conclusion RFCA can signiifcantly reduce LA diameter and forming heart failure in patients with paroxysmal and permanent.
