Corrected Transposition of the Great Arteries

To the Editor: Corrected transposition of the great arteries without associated intracardiac anomalies is a very rare condition.1 This lesion is also known as ventricular inversion with l-transposition. As with complete or d-transposition, the aorta arises from the right ventricle and the pulmonary artery from the left ventricle (Figure 1), but in corrected transposition of the great arteries there is also ventricular inversion, so that the “right ventricle” is on the left side of the heart and is connected to the left atrium. Thus, pulmonary venous return to the left atrium flows to the morphologic right ventricle and is then . . .
