High risk anatomic features of right-ACAOS with IAC on CCTA—CCTA-identified right-ACAOS features. (1) 3D image depicting anomalous origin of the coronary artery arising from the opposite sinus with interarterial course between aorta and pulmonary artery. (2) Intramural location and take-off angles obtained in multiplanar axial reconstructions at the level of the ACAOS ostium. (3) Slit-dlike morphology. Lumen diameters obtained in double oblique view, taking the maximum and minimum diameters of the vessel at the most narrowed proximal location (A) and the distal reference (B). A–B distance represents the interarterial course length of the anomalous vessel. ACAOS anomalous origin of the coronary artery arising from the opposite sinus; CCTA coronary computed tomography angiography; IAC interarterial course.
