Anatomic correction in transposition of the great arteries with unusual coronary pattern and side-by-side location.

Switch operation is the treatment of choice in infants with transposition of the great arteries. The anatomic correction restores the left ventricle to its normal systemic function. In complete transposition, however, the diverse spectrum of coronary pattern influences the surgical outcome. We describe a successful arterial switch operation without LeCompte manoeuvre in a neonate with unusual coronary artery anatomy and side-by-side great arteries.
