Introduction Congenital coronary artery anomalies (CAAs) are rare structural variations affecting the origin and course of coronary vessels, reported in 0.2–1.3% of invasive angiographies and up to 5.6% of computed tomography (CT) coronary angiography studies.1 Although most variants are benign, those involving an inter-arterial course between the great arteries may result in myocardial ischaemia, arrhythmias or sudden cardiac death.2 Anomalous origin of the left anterior descending (LAD) artery from the right coronary sinus is extremely uncommon, with clinical implications depending largely on its anatomical trajectory.3 Herein, we present
