4.4 Patterns of Coronary Anomalies in Transposition of the Great Arteries

Normally the coronary arteries arise from the sinuses facing the pulmonary artery. In patients with transposition of the great arteries this is also the case but because the great vessels are transposed the coronaries typically arise from the left and non-coronary sinuses instead of the right and left coronary sinuses. We will show the patterns of coronary artery anomalies seen in transposition of the great arteries.

Fig. 4.4Intraluminal 3D (3-D) reconstruction (a) and lateral view from a volume-rendered 3-D image (b) from a cardiac CTA in an infant with known D-TGA again shows the typical pattern of coronary artery origins with the right coronary artery (RCA) arising from the noncoronary sinus (NCS) and the left coronary artery (LCA) arising from the left coronary sinus (LCS). Notice that there is no coronary artery arising from the right coronary sinus (RCS) because it is not one of the two sinuses facing the pulmonary artery
