Abstract

We present a case of prenatally diagnosed d-transposition of the great arteries (d-TGA) with intact ventricular septum (IVS), postnatally found to have bilateral patent ductus arteriosus (PDA) with potential for isolation of the left subclavian artery (LSA) and an abnormal left coronary artery (LCA) course. Isolation of the LSA is a rare occurrence and defined as an anomalous origin from the pulmonary artery via PDA and apparent discontinuation from the arch following PDA closure. It is exceedingly rare in association with d-TGA. Coronary artery anatomy is particularly important in d-TGA given most patients undergo the arterial switch operation (ASO).
