摘　　要：经食管超声心动图是诊断左心耳血栓的"金标准",心脏声学造影结合能量多普勒、心脏CT延迟成像、二维增强单相心脏CT等检测左心耳血栓的敏感性和特异性也都非常高。左心耳血流速度降低、左心耳壁运动速度降低、左心耳射血分数降低、左心耳应变降低、左心室肥大、左心室射血分数降低、左心房增大等都是左心耳血栓的预测因子,有助于指导心房颤动患者的抗凝治疗和预防血栓栓塞事件。Transesophageal echocardiographic（ TEE） is ″gold standard″ of detection of left atrial appendage thrombus. The sensitivity and specificity of contrast echocardiography（ CE） combined with power Doppler imaging（ PD）,cardiac CT delayed imaging and dual-enhancement single-phase cardiac computed tomography are also very high for the detection of left atrial appendage thrombus. Reduced left atrial appendage flow velocity,lower left atrial appendage wall motion velocity（ LAAWV）,lower Left atrial appendage emptying fraction（ LAAEF）,left ventricular hypertrophy,lower left atrial appendage strain,lower left ventricular ejection fraction（ LVEF） and increased left atrial volume are all predictors of left atrial appendage thrombus,and helpful to guide anticoagulant therapy and prevent thromboembolic events in the patients with atrial fibrillation.
