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.

Right aortic arch with common origin of right carotid and left innominate artery: A case report

“…The prevalence of aortic arch anomalies is between 0.5 and 3.0% 5 . Aortic arch anomalies are commonly associated with congenital heart defects, chromosomal abnormalities, and esophageal or tracheal compression symptoms 6–8 …”

“…5 Aortic arch anomalies are commonly associated with congenital heart defects, chromosomal abnormalities, and esophageal or tracheal compression symptoms. [6][7][8] RAA occurs when the aortic arch traverses over the right bronchus instead of the left and descends along the right side of the spine. The RAA is present in 0.01%-0.1% of the general population.…”
