Interarterial course of anomalous aortic origin of coronary artery (AAOCA) is the most frequent form found on autopsy of young patients who experienced sudden cardiac death. Patients dying of AAOCA often have an intramural coronary segment crossing the aortic wall with elliptic luminal narrowing. Fractional flow reserve–computed tomography (FFR-CT) imaging offers evaluation of the hemodynamic impact of coronary stenosis by modeling stress blood flow and might represent an interesting imaging approach in AAOCA.
