点消融治疗典型心房扑动的疗效

Effect of points ablation on typical atrial flutter

目的探讨点消融法治疗典型心房扑动的疗效。方法将16例典型心房扑动患者随机分为两组,线性消融组(A组)与点消融组(B组)。比较两组下腔静脉与三尖瓣峡部双向阻滞的手术时间、X线照射时间、放电次数、手术费用、复发率。结果与线性消融组比较,点消融组患者的手术时间、X线照射时间短,放电次数少,手术费用低(P<0.01)。两组均未发生心包填塞、Ⅲ度房室传导阻滞以及栓塞等并发症。两组复发率的差异无统计学意义。结论点消融是一种值得进一步推广的治疗典型心房扑动的方法。

Objective To explore the effect of points ablation on typical atrial flutter （AFL）. Methods Sixteen patients with typical AFL were randomly dividied into line ablation group （group A, 10 cases ） and points ablation group （group B, 6 cases）. The procedure duration, fluoroscopy duration, times of radiofrequency energy application, expense of procedure and recurrence rate in both groups were compared. Results The durations of procedure and fluoroscopy in group B were significantly shorter than those in group A （P 〈0.01 ）. The times of radiofrequeney energy application and expense of procedure in group B were significantly less than group A（ P 〈 0.01 ）. There was no significant difference in recurrence rate between two groups. No serious complications such as pcricardial effusion, embolism were found. Conclusion Points ablation is a good procedure for typical AFL, and it is worth being extended.
