摘　　要：目的探讨多平面经食管超声心动图(transesophageal echocardiography,TEE)诊断法洛四联症的最佳显示方位和切面。方法将可视化心脏与多平面TEE进行对照研究,确立多平面TEE诊断法洛四联症的最佳方位和常用切面。结果多平面TEE观察肺动脉情况的最佳切面是食管上段0°方位的肺动脉主干和分叉切面;观察室间隔缺损和主动脉骑跨的最佳显示切面是食管中段0°方位五腔心切面;观察右心室壁和右室流出道狭窄的最佳切面是食管中段45°方位的右室流出道切面;观察室间隔缺损和主动脉骑跨的最佳显示切面是食管中段135°方位的左室长轴切面。结论可视化心脏模型与多平面TEE进行对照研究所确立的多平面TEE最佳方位和常用切面,简化了诊断法洛四联症的操作过程,缩短了检查时间。Objective To find out the best orientations and sections in diagnosing tetralogy of Fallot using multiplane transesophageal echocardiography （TEE）. Methods The visible heart was compared with the images of muhiplane TEE to determine the best orientations and sections in the muhiplane TEE for tetralogy of Fallot. Results The best orientation and section of pulmonary artery and its branches in muhiplane TEE was the pulmonary artery viewed at 0° from the upper part of esophagus ; that of ventricular septal defect and aortic overriding were five chambers viewed at 0° from the middle part of esophagus or the left ventricle long-axis view at 135° from the middle and end parts of the esophagus; that of the right ventricular outflow tract stenosis and the right ventricular hypertrophy was the right ventricular outflow tract long-axis viewed at 45° from the middle part of esophagus. Conclusion The best orientations and sections in TEE based on the visible heart are helpful to simplify the operation procedure of muhiplane TEE and to shorten the examination time.
