Vascular ring associated with d-transposition of the great arteries: when should we suspect aortic arch anomalies?

Abstract

A male neonate with d-transposition of the great arteries was diagnosed with the concomitant anomaly of left circumflex aortic arch and right-sided ductus arteriosus, which formed a vascular ring. Initial postnatal echocardiography had demonstrated an obscured aortic isthmus mimicking coarctation of the aorta, which could be a diagnostic clue to circumflex aortic arch.
