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

Introduction For many years, the exercise tolerance test (ETT) has been the first-line investigation in patients presenting with stable chest pain. However, equivocal and false-positive results often lead to additional investigations. In recent years, computed tomography (CT) coronary angiography (CTCA) has been demonstrated to have excellent negative predictive value, making it a useful test to rule out obstructive coronary artery disease (CAD).1-3 In 2010, the UK National Institute for Health and Care Excellence (NICE) published clinical guideline 95: ‘Chest pain of recent onset’. This guideline advocates the use of a new risk estimatio
