目的:评估三尖瓣峡部消融对伴有典型心房扑动(房扑)和不伴典型房扑发作的心房颤动(房颤)患者术后复发的影响。方法:连续入选房颤射频消融治疗患者113例,根据有无典型房扑分为三尖瓣峡部消融组(CTI组)和未行三尖瓣峡部消融组(Non-CTI组),比较临床特征及手术特点,并随访术后典型房扑和房颤发生率。结果:Non-CTI组左房内径更大,持续性和永久性房颤的比例、左房线性消融的比例更高。而CTI组射频消融时间较Non-CTI组更长。术后典型房扑和房颤发生率2组无显著区别。结论:无典型房扑发作的房颤患者,不行三尖瓣峡部消融,不会升高术后典型房扑发生率和房颤复发率,同时射频消融时间缩短。
PURPOSE: To evaluate the effect of tricuspid isthmus ablation on postoperative recurrence in patients with atrial flutter (atrial fibrillation) and typical atrial flutter (atrial flutter) without atrial flutter. Methods: A total of 113 consecutive patients undergoing radiofrequency ablation of atrial fibrillation were enrolled in this study. Tricuspid isthmus ablation group (CTI group) and non-Tricuspid isthmus ablation group (Non-CTI group) And surgical characteristics, and followed up the incidence of typical atrial flutter and atrial fibrillation. Results: In non-CTI group, the left atrial diameter was larger, the ratio of persistent and permanent atrial fibrillation was higher, and the ratio of left atrial linear ablation was higher. The CTI group radiofrequency ablation time longer than Non-CTI group. There was no significant difference between the two groups after typical atrial flutter and atrial fibrillation. Conclusion: Atrial fibrillation without atrial flutter in patients with atrial fibrillation, not the tricuspid isthmus ablation, does not increase the incidence of postoperative atrial flutter and atrial fibrillation recurrence rate, shortening the time of radiofrequency ablation.
