Although right aortic arch (RAA) is a rare developmental anomaly, it can create a challenging anatomical situation while cannulating coronaries working through right transradial approach (TRA). We describe a rare adult patient with mirror-image RAA, whose coronary angiogram was performed through right TRA. We have also discussed the challenges encountered because of RAA and technique to enter the ascending aorta.
