摘要
目的评价导管消融治疗持续性心房颤动伴左室功能不全的疗效。方法回顾分析连续10例接受导管消融的持续性心房颤动伴左室功能不全患者,短期随访观察术前、术后心功能的改变。结果9例患者成功完成导管消融术,术前平均左室射血分数(LVEF)0·41±0·01,左室舒张末期内径(LVEDD)56·00±7·21mm,左心房内径(LAD)44·22±5·91mm。术后平均随访2·78±1·78个月,平均LVEF增为0·46±0·06,LVEDD降为53·33±6·42mm,LAD降为42·11±4·65mm,与术前相比差异有统计学意义(P<0·05)。结论在慎重选择病例的基础上,导管消融术治疗持续性心房颤动伴左室功能不全安全、有效。
Objective To evaluate the effect of catheter ablation for atrial fibrillation on left ventricular function in patients with heart failure. Methods We retrospectedly studied 10 consecutive patients with congestive heart failure and a left ventricular ejection fraction of less than 45 percent who underwent catheter ablation for atrial fibrillation. The change in left ventricular function before and after catheter ablation was monitored during a short-term follow-up period. Results Nine patients underwent catheter ablation successfully. After a mean （SD） of 2. 78 ± 1.78 months, the patients showed improvement in left ventricular function through improvement in the left ventricular ejection fraction from 0.41 ±0. 01 to 0. 46±0. 06, the left ventricular diastolic diameter decreased from 56. 00±7.21 mm to 53.33±6. 42 mm and the left atrial diameter decreased from 44. 22±5.91ram to 42. 11 ±4. 65 ram, P 〈0. 05. Conclusion Catheter ablation is safe and effective for treating atrial fibrillation in carefully selected patients with left ventricular dysfunction.
