左心耳封堵术:预防心房颤动左心耳血栓的利刃

摘要

血栓栓塞性并发症是心房颤动致死、致残的主要原因，左心耳是心房颤动患者血栓形成的主要部位。抗凝及外科手术切除左心耳副作用及创伤大，患者难以接受。经皮导管介入行左心耳封堵术是近年来进展快速的预防心房颤动血栓栓塞的方法，具有创伤小、操作简单、耗时较少等优点。作者对国内外左心耳封堵术的相关研究进展作一介绍。%Thromboembolic complication is the main cause of death and disability during atrial fibrillation .Left atrial appendage in patients with atrial fibrillation is the position of the thrombus for-mation.Patients are not tolerated with side effects or trauma by treatment with anticoagulant or resec-tion of the left atrial appendage .The methods with percutaneous left atrial appendage transcatheter occlusion become popular and developed rapidly in recent years for prevention of thrombus formation in atrial fibrillation for advantage with little trauma , easy operated and less time-consuming .The re-search progress on left atrial appendage occlusion at home and abroad was reviewed .
