Double Aortic Arch in D-Transposition of the Great Arteries: Confirmation of Dominant Arch by Magnetic Resonance Imaging

We report the case of a female infant who had the rare combination of double aortic arch and D-transposition of the great arteries. The double aortic arch was diagnosed at the time of her arterial switch procedure. Magnetic resonance imaging identified the left arch as dominant, and the right arch was successfully ligated.
