Figure 1. Axial maximum intensity projection CT angiography image of TGA following an ASO with the LeCompte maneuver. The branch pulmonary arteries bifurcate anterior to the ascending aorta and ‘drape over’ it. The great arteries are lying directly in antero-posterior relation and the right and left branch PA sizes are balanced.

ASO: arterial switch operation, CT: computed tomography, TGA: transposition of the great arteries.
