Transesophageal echocardiography (TEE) demonstrated the left main coronary trunk in 30 of 32 patients. Of these 30 patients, 10 had angiographically normal and 20 stenotic left main coronary arteries. The TEE study revealed no stenosis in 9 of 10 patients with normal left main trunks and atherosclerotic lesions in all 20 patients with stenotic left main trunks. TEE demonstrated additional areas of stenosis in the left main coronary artery in 3 patients, which included ostial lesions in 2 patients. These features were not observed by angiography. Furthermore, when compared with angiography, TEE overestimated severity of stenosis in 4 patients. In conclusion, TEE is a useful test in demonstrating normal as well as stenotic left main coronary trunks.
经食管超声心动图（TEE）在32例患者中的30例显示了左冠状动脉主干。在这30例患者中，10例左冠状动脉主干血管造影正常，20例左冠状动脉主干狭窄。TEE研究显示，10例左冠状动脉主干正常的患者中有9例无狭窄，20例左冠状动脉主干狭窄的患者均有动脉粥样硬化病变。TEE在3例患者中显示左冠状动脉主干有额外的狭窄区域，其中2例为开口处病变。血管造影未观察到这些特征。此外，与血管造影相比，TEE高估了4例患者的狭窄严重程度。总之，TEE在显示正常以及狭窄的左冠状动脉主干方面是一项有用的检查。
