Abstract

Coronary artery anomalies are uncommon in the general population. The most frequently reported anomaly involving the circumflex artery is its origin from the right aortic sinus or the right coronary artery. However dual circumflex artery is an extremely rare anomaly. We report a case of a 79-year-old male patient who was admitted to our centre with a diagnosis of severe aortic stenosis, scheduled for transcatheter aortic valve implantation. Computed tomography angiography revealed dual circumflex arteries: one originating normally from usual bifurcation of the left main coronary artery and an accessory one arising separately from the left main coronary artery stem proximal to the bifurcation.
