摘　　要：目的应用实时三维经食管超声心动图(RT3D-TEE)评价非瓣膜性心房颤动(AF)患者左心耳(LAA)形态及功能。方法通过经胸超声心动图及RT3D-TEE采集图像,对29例心房颤动患者(AF组)和12例无器质性心脏疾病受试者(对照组)的LAA形态和功能进行比较。结果 AF组LAA口短径及左心耳舒张末期容积(LAA-EDV)测值显著高于对照组(P=0.01、0.02);AF组LAA的峰值血流排空速度,LAA口离心率和LAA射血分数均显著低于对照组(P=0.01、0.01、0.02)。结论与对照组相比,AF组LAA形态和功能有明显差异;应用RT3D-TEE对LAA进行形态和功能研究是可行的。Objective To observe the morphology and function of the left atrial appendage （LAA） using real-time three-dimensional transesophageal echocardiography （RT3D-TEE） in patients with non-valvular atrial fibrillation （AF）. Methods Images of 29 atrial fibrillation patients （AF group） and 12 patients without organic heart disease （control group） were obtained using transthoracic echocardiography and RT3D-TEE. The differences of LAA morphology and mechanical function between the two groups were compared. Results LAA short diameter and end-diastolic volume in AF group were higher than those in control group （P=0.01, 0.02）. LAA peak emptying velocity （PEV）, LAA eccentricity and LAA ejection fraction （EF） in AF group were obviously lower than those in control group （P=0.01,0.01,0.02）. Conclusion There were differences in size and function of LAA between AF group and control group. Quantitative analysis of the size and function of LAA with RT3D-TEE is feasible.
