Anomalous origin of the coronary artery from the opposite sinus of Valsalva (ACAOS) is a rare inborn disease that is characterised by an anomalous course and/or termination of a native coronary vessel.1,2 The traditional definition of ACAOS differentiates between benign and malignant variants. Malignant ACAOS has an interarterial course (IAC) of the anomalous vessel between the pulmonary artery and the aorta. Benign variants represent all other courses, such as in front of the pulmonary artery (prepulmonic) or a retroaortic course.2 The term malignant originates from autopsy studies in young athletes, where ACAOS with IAC was found to be a potential underlying cause of sudden cardiac death (SCD).3 It is suggested that people with ACAOS and IAC may be at risk for myocardial ischaemia and consecutive arrhythmia, even in the absence of atherosclerotic lesions, as the anomalous vessel is prone to dynamic compression during physical exercise. Beside the classical malignant variant of ACAOS with IAC, other anatomic high-risk features are known, such as a slit-like ostium, acute take-off angle, or an intramural course where the proximal part of the anomalous vessel passes in the tunica media of the aortic wall, with proximal narrowing and an elliptic vessel shape.1,4

An interarterial course of the left coronary artery is defined as origination of the left main or left anterior descending coronary artery from the right coronary sinus of Valsalva, with a course between the ascending aorta and the pulmonary artery trunk.
