Illustration of CAD presence in different AAOCA. Panel A: CT image of a circumflex artery (black arrow) arising from the right sinus and associated with a retroaortic course. Presence of a calcified plaque (white arrow) on the ectopic segment. Panel B: CT image of a right coronary artery (black arrow) arising from the left sinus and associated with an interarterial course. Presence of a calcified plaque (white arrow) on the nonectopic segment. To note, the ectopic segment is free from CAD.
