目前,心房颤动(简称房颤)消融最基本的策略是肺静脉隔离。然而,对于持续性或永久性房颤,常常需要同时消融肺静脉以外的区域,比如上腔静脉、冠状静脉窦、Marshall韧带以及左房后壁等部位。最近一项发表在Circulation杂志上的研究显示:左心耳在部分房颤的发生机制中起到重要作用,隔离左心耳有利于提高房颤消融的成功率。

At present, the most basic strategy for ablation of atrial fibrillation (atrial fibrillation) is pulmonary vein isolation. However, for persistent or permanent atrial fibrillation, it is often necessary to simultaneously ablate areas beyond the pulmonary veins, such as the superior vena cava, the coronary sinus, the ligament of Marshall, and the posterior wall of the left posterior chamber. A recent study published in the Circulation Journal showed that the left atrial appendage plays an important role in the pathogenesis of partial atrial fibrillation. Isolating the left atrial appendage helps to improve the success rate of atrial fibrillation ablation.
