Anomalous Origin of the Right Subclavian Artery in a Patient with D-transposition of the Great Arteries

Hyojung Park et al. Korean J Thorac Cardiovasc Surg. 2018 Dec.

Abstract

This case report concerns a young patient with an extremely rare combination of d-transposition of the great arteries (d-TGA) and anomalous origin of the right subclavian artery. In our patient, the right subclavian artery originated from the pulmonary artery, which is why he did not show reversed differential cyanosis. We conclude that the presence of an aortic arch anomaly should be considered in patients with d-TGA who do not present with reversed differential cyanosis. A further imaging work-up, including computed tomography or magnetic resonance imaging, might be helpful.

Keywords: Anomalous origin of right subclavian artery; Reversed differential cyanosis; Transposition of the great arteries.
