The frontal chest film as a means of suspecting transposition complexes is discussed. The first step is recognizing the normal relationships formed by the ascending aorta, an aortic knob-descending aorta, and pulmonary trunk. The concept of which ventricle is connected to which atrium is developed--the terms ventricular noninversion and inversion being utilized. Frontal chest film signs of transposition are summarized as follows: 1) in the majority of transposition complexes, absence of the pulmonary trunk is the premier sign; 2) patients with ventricular noninversion tend to show the ascending aorta and aortic knob-descending aorta in normal position. Patients with ventricular inversion usually show absence of all three great artery relationships. 3) In ventricular inversion, the left heart border shows a septal notch or a diffuse convex bulge (two ventricles), or a discrete bulge high up on the left border (single ventricle).
本文讨论了胸部正位片作为怀疑大动脉转位复合体的一种手段。第一步是识别升主动脉、主动脉弓 - 降主动脉和肺动脉干所形成的正常关系。阐述了哪个心室与哪个心房相连的概念，采用了心室不反位和反位这两个术语。大动脉转位的胸部正位片征象总结如下：1）在大多数大动脉转位复合体中，肺动脉干缺如是首要征象；2）心室不反位的患者往往表现为升主动脉和主动脉弓 - 降主动脉位置正常。心室反位的患者通常表现为所有三大动脉关系均缺失。3）在心室反位时，心脏左缘显示有室间隔切迹或弥漫性凸隆（两个心室），或在左缘上方有一个孤立的凸隆（单心室）。
