A 15-year-old boy presented with exertional palpitations and chest pain. Investigation revealed anomalous origin of his left anterior descending coronary artery from his pulmonary trunk causing myocardial ischaemia. He previously had aortic coarctation repair with known aortic root dilation and a bicuspid aortic valve. His left anterior descending artery was implanted into the aortic root using a Gortex interposition conduit. This represents an interesting combination of cardiac abnormalities for which repair required consideration of the requirement of further surgery in the future.
