title: Detection of a double right coronary artery with 16-row multidetector computed tomography.
abstract: We present the case of a 46-year-old male patient with known history of coronary artery disease and recurrent episodes of angina pectoris. Coronary angiography revealed two vessels originating from the right coronary sinus. However, a clear distinction between a double RCA and a high take off of a large right ventricular branch could not be made. Contrast-enhanced MDCT was performed on a 16-row scanner which clearly depicted cardiac anatomy and finally established the diagnosis of a double RCA. To our knowledge, this is the first report of a true double RCA diagnosed by MDCT.
