心房颤动(房颤)是目前临床上最普遍发生的心律失常之一,随着患者年龄的增长,其发病率及病死率逐渐升高~[1]。长期的持续性房颤将会导致心房内血流动力学发生不良改变,左心耳血栓是其最常见的并发症。房颤发生时左心耳内的血栓脱落是血栓栓塞的主要危险因素,大量报道证实脱落的血栓与脑卒中事件有很强的相关性,约占缺血性卒中的15%~[2-3]。CHA2DS2-VASc评分是评价左心耳血栓形成及脑卒中发生风险的重要指标~[4],本
Atrial fibrillation (atrial fibrillation) is one of the most common cardiac arrhythmias in clinical practice. As the patient’s age increases, its morbidity and mortality gradually increase [1]. Long-term persistent atrial fibrillation will lead to adverse changes in atrial hemodynamics, left atrial appendage thrombosis is its most common complication. Atrial fibrillation occurs when left atrial appendage thrombus shedding is the main risk factor for thromboembolism, a large number of reports confirm the shedding of thrombus and stroke events have a strong correlation, accounting for about 15% of ischemic stroke [2-3] . CHA2DS2-VASc score is to evaluate the left atrial appendage thrombosis and stroke risk an important indicator of ~ [4], the
