Coronary artery abnormalities are a serious complication following the arterial switch operation (ASO) for d-transposition of the great arteries (TGA). While CTA optimally visualizes the coronaries, prior studies have found potentially high-risk coronary lesions in asymptomatic s/p ASO patients, raising questions about when CTA is warranted. CMR is commonly used for monitoring after the ASO, offering assessment without radiation. However, its utility for coronary evaluation remains unclear. We aimed to (1) compare the indications and outcomes of CMR vs. CTA after ASO, and (2) compare coronary features between modalities. Read More
