Abstract: 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.
