Transesophageal echocardiography (TEE) is superior to transthoracic echocardiography (TTE) in evaluating the left atrial appendage (LAA) as a potential cardiac source of embolus in patients with stroke. We describe two such patients in whom a TEE and subsequently a three-dimensional (3-D) reconstruction of the LAA were performed. These case reports show that 3-D echocardiography provides better visualization of LAA anatomy, and that a 3-D description of LAA morphology may be the basis of describing normal and abnormal LAA.
在评估左心耳（LAA）作为中风患者潜在心脏栓子来源方面，经食管超声心动图（TEE）优于经胸超声心动图（TTE）。我们描述了两名接受TEE检查并随后对LAA进行三维（3-D）重建的患者。这些病例报告表明，三维超声心动图能更好地显示LAA的解剖结构，并且LAA形态的三维描述可能是描述正常和异常LAA的基础。
