Abstract :
Double right coronary artery arising from a single ostium in the right sinus of Valsalva is an extremely rare coronary artery variation. Differentiating this variation from high take off of a large right ventricular branch is often difficult in conventional coronary angiography. In two cases, multidetector-row computed tomography (MDCT) identified double right coronary artery. MDCT allows three-dimensional comprehension of the coronary artery anatomy and it is thought to be useful to distinguish this variation from a large right ventricular branch.
