心房纤维颤动(房颤)是最常见的心律失常之一，房颤患者发生脑卒中的风险很大。口服抗凝药物预防脑卒中存在出血风险，部分患者不能耐受。经皮左心耳封堵在房颤患者预防脑卒中方面安全有效，目前还只适用于存在抗凝禁忌的患者。本文回顾了近年来应用的多种左心耳封堵装置，分析不同形状设计的装置与左心耳形态的关系。

Clinically, atrial fibrillation (AF) is one of the most common cardiac arrhythmia, and patients with arterial fibrillation carry high risk of stroke. Oral administration of anticoagulation such as warfarin for the prevention of stroke has some risks to induce bleeding; moreover, some patients are not able to tolerate the medication. Percutaneous occlusion of the left atrial appendage is safe and effective for the prevention of stroke in patients with atrial fibrillation, although at present it is only used for the patients who have contraindications to anticoagulation medication. This paper aims to review a variety of left atrial appendage occlusion devices and to analyze the relationship between the different shape design of occluder and the left atrial appendage morphology.
