心房颤动(房颤)是临床最常见的持续性心律失常,会增加血栓栓塞的风险。来源于左心耳的血栓是导致房颤患者栓塞的主要原因。经皮左心耳封堵术作为一项新的预防血栓栓塞的技术,为存在高出血风险而无法服用抗凝药的房颤患者提供了更多的选择。近年来的研究表明左心耳封堵术可显著降低卒中的发生率。文中通过回顾左心耳封堵术相关的研究,从而探讨左心耳封堵术预防房颤血栓栓塞的安全性、有效性。
Atrial fibrillation (AF) is the most common persistent arrhythmia in the clinic and increases the risk of thromboembolism. Thrombus from the left atrial appendage is the main cause of embolism in patients with atrial fibrillation. Percutaneous auricular closure is a new technique for thromboembolism prevention and provides more options for patients with AF who are at high risk of bleeding who can not take anticoagulants. In recent years, studies have shown that left atrial appendage occlusion can significantly reduce the incidence of stroke. In this paper, by reviewing the left atrial appendage occlusion related studies, to explore the safety and effectiveness of the left atrial appendage occlusion in prevention of atrial fibrillation thromboembolism.
