随着医疗水平发展,人工瓣膜植入数量与日俱增,其中,瓣膜病合并心房颤动患者占比较高~([1])。心房颤动是临床常见的心律失常之一,可明显影响患者心功能,其主要危害为左心房血栓形成~([2-3])。据统计,瓣膜病合并心房颤动患者中,约60%血栓在左心耳内形成~([4])。左心耳内血栓脱落是造成脑动脉栓塞的主要原因[5],脑动脉栓塞起病急、进展快、后果严重,给患者带来非常严重的后果。非瓣膜性心房颤动患者采用左心耳缝扎在预防血栓发
With the development of the medical level, the number of artificial valve implantation is increasing day by day. Among them, valvular disease has a higher proportion of patients with atrial fibrillation (1). Atrial fibrillation is one of the common clinical arrhythmias, which can significantly affect the cardiac function of patients. The main risk is atrial thromboembolism ([2-3]). According to statistics, about 60% of patients with valvular disease and atrial fibrillation develop thrombus in the left atrial appendage ~ ([4]). Left atrial appendage thrombus shedding is the main cause of cerebral arterial embolism [5], cerebral arterial embolism acute onset, rapid progress, serious consequences, to patients with very serious consequences. Non-valvular atrial fibrillation patients with left atrial appendage suture in the prevention of thrombosis
