Objective : to investigate effectiveness of using live three - dimensional transthoracic echocardiography to exam left atrial appendage 摘要目的：探讨实时三维超声心动图对左心耳形态观察的有效性。
4.
Methods : live three - dimensional transthoracic echocardiography images were obtained in 22 suitable patients referred to our department for routine transthoracic echocardiography 方法：对22例因多种适应证接受常规二维超声心动图检查的患者用实时三维探头进行经胸三维观察左心耳形态。
5.
Conclusion : live three - dimensional transthoracic echocardiography is a useful method to exam left atrial appendage , its diagnostic value is nearly equal to transesophageal echocardiography if a good image was obtained 结论：用实时三维探头经胸观察左心耳是一种有效的检查手段，对于超声图像显示满意的患者，左心耳形态学的观察接近食管超声心动图的诊断价值。
