Fig. 7 Anomalous circumflex in d-TGA. Laid-back aortogram shows a rightward anterior aorta and 2 coronaries arising from the mid-points of their respective facing sinuses. The right coronary artery (RCA) gives off the circumflex (CX), which travels a retropulmonary course to reach the left atrioventricular groove.

ANT = anterior; d-TGA = complete transposition of the great arteries; LAD = left anterior descending; LCA = left coronary artery; R = right
