Answer

Cardiovascular magnetic resonance imaging (CMRI) is a good, noninvasive, radiation-free investigation in the postsurgical evaluation of ALCAPA. In referred patients, basal, anterolateral subendocardial myocardial fibrosis is a characteristic finding. Furthermore, stress adenosine CMRI perfusion, can identify reversible ischemia in this group, and is indicative of left coronary artery occlusion. [12]
