摘　　要：三尖瓣峡部是典型房扑折返环中的缓慢传导区域,对这一解剖结构进行线性消融以达到双向传导阻滞是典型房扑的一线治疗方法。房颤与典型房扑内在关系密切,一方面房颤与典型房扑往往共存于同一患者,另一方面房颤患者在电生理检查中常可见到典型房扑的诱发。因此在房颤射频消融术中常常补充三尖瓣峡部线性消融,以期病人获得更好的远期预后。但最近的研究对这一术式的疗效提出了质疑。本文以两种心律失常的内在联系为切入点,就三尖瓣峡部消融在房颤射频消融术中的疗效进行综述。The cavotricuspid isthmus is the slow conduction region in the reentrant loop of typical atrial flutter. To reach bi-directional conduction block, linear ablation of this anatomical structure has been recognized as the first-line procedure for typical atrial flutter. It is known to us that atrial fibrillation is closely related to typical atrial flutter: on the one hand, they often coexist in the same patient;on the other hand, typical atrial flutter is usually inducible in electrophysiological examination procedure in patients who are suffering atrial fibrillation. Therefore, physicians usually supplement cavotricuspid isthmus ablation to atrial fibrillation ablation procedure in order to obtain better long-term prognosis. Nevertheless, recent studies have cast doubt on the effectiveness of this linear ablation procedure. In this article, taking the relationship of these two kind of ’Af’ as a starting point, we review the therapeutic effect of cavotricuspid isthmus linear ablation in the radiofrequency ablation procedure of atrial fibrillation.
