Several cardiac and aortic findings on TEE have been implicated as sources for systemic emboli. These findings include left atrial thrombus, left atrial spontaneous contrast, patent foramen ovale, atrial septal aneurysm, and aortic atheroma. The prevalence of each of these abnormalities has been significantly greater in patients with suspected embolic events as compared with controls. Furthermore, the sensitivity of TEE for these findings is much greater than that of TTE. Thus, patients with unexplained cerebral ischemia or systemic emboli should undergo TEE so that possible sources can be detected. In regard to cardiac tumors, although the data are preliminary, certain tumor locations and morphologic aspects are better evaluated with TEE than with other techniques. More importantly, it has been suggested that a change in management of cardiac tumors is initiated by TEE in the majority of instances. TEE provides important diagnostic information in many patients with suspected cardiac emboli and cardiac masses and should be strongly considered in the work-up of such patients.
经食管超声心动图（TEE）检查发现的一些心脏和主动脉病变被认为是系统性栓塞的来源。这些病变包括左心房血栓、左心房自发显影、卵圆孔未闭、房间隔瘤和主动脉粥样硬化。与对照组相比，疑似栓塞事件患者中这些异常情况的发生率显著更高。此外，TEE对这些病变的敏感性远高于经胸超声心动图（TTE）。因此，患有不明原因脑缺血或系统性栓塞的患者应接受TEE检查，以便检测可能的栓子来源。关于心脏肿瘤，虽然数据尚属初步，但某些肿瘤位置和形态学特征通过TEE评估比其他技术更好。更重要的是，有人提出，在大多数情况下，TEE会引发心脏肿瘤治疗方案的改变。TEE为许多疑似心脏栓塞和心脏肿块的患者提供重要的诊断信息，在对此类患者的检查中应强烈考虑使用TEE。
