Clinical application evaluation and progress of different left atrial appendage occlusion devices / 中国医师杂志

Atrial fibrillation is the most common cause of cardiogenic stroke. At present, oral anticoagulation is regarded as a better choice to prevent thrombosis for reducing the risk of stroke. Percutaneous left atrial appendage closure is an effective alternative to prevent thromboembolic events in non-valvular atrial fibrillation patients who have contraindications to anticoagulation or do not tolerate anticoagulant therapy, or still have repeated embolization after anticoagulation. This article reviews the safety of several different left atrial appendage closure devices used in surgery for patients with atrial fibrillation and compares their postoperative stroke risk.
