Why the study?
Coronary perfusion dictates outcomes after arterial switch operation for transposition of the great arteries, but coronary CTA is not yet routinely used in these patients.
Does CCTA accurately identify acquired coronary anomalies compared to conventional angiography in patients with transposition of the great arteries after an arterial switch operation?
Does CCTA accurately identify acquired coronary anomalies compared to conventional angiography in patients with transposition of the great arteries after an arterial switch operation?
CCTA accurately identifies iatrogenic postoperative coronary lesions in patients with transposition of the great arteries after an arterial switch operation, appearing superior to conventional angiography.

CCTA may detect more post-ASO coronary lesions than angiography; leaves open whether routine use improves outcomes in this population.
