摘　　要：左心耳自发显影是心房颤动患者具有的一种常见超声心动图表现,特征是左心耳内有漩涡状或云雾状的回声,它的形成主要与左心耳内血流淤滞、左心耳及心脏解剖结构、临床心血管疾病危险因素及相关生物学指标等密切相关,是心房颤动患者心源性卒中的独立危险因素。准确评价左心耳自发显影在预防卒中及栓塞等方面有重要意义。Spontaneous echo contrast of left atrial appendage is a common echocardiographic manifestation in patients with atrial fibrillation.It is characterized by swirling or smoke-like echoes in left atrial appendage.Its formation is closely related to left atrial appendage blood flow stasis,left atrial appendage and cardiac anatomic structure,clinical cardiovascular disease risk factors and related biological indicators,and they are independent risk factors for cardiogenic stroke in patients with atrial fibrillation.Accurate evaluation of left atrial appendage spontaneous echo contrast is of great significance in preventing stroke and embolism.
