| 摘要: |
| 左心耳是原始胚胎左心房的残余，是肺静脉血液回流入左心室的通道，其内部由丰富的梳状肌及肌小梁等构成，外观呈入口窄中间宽的盲端结构，是附壁血栓的好发部位，也是心源性脑卒中栓子的重要来源。超声心动图运用各项新技术的优势来评价左心耳形态、结构及血流动力学变化，可以前期预测和评估血栓栓塞的风险性。 |

| Abstract: |
| The left atrial appendage is the remnant of the left atrium of the original embryo and the passage of the pulmonary venous blood into the left ventricle. It is composed of the rich comb muscle and the muscle trabecula. The appearance shows a blind end structure with narrow and wide entrance. It is a good location of the thrombus and an important source of the embolus of the apoplexy of the heart. Echocardiography uses the advantages of various new techniques (CDFI, TDI, STI, VFM, VVI, CS, 3D-ECH) to evaluate the changes of left atrial appendage, structure and hemodynamics, which can predict and evaluate the risk of thromboembolism in the early stage. |
