Aberrant origin of the right ventricular coronary artery: A case report.

This case describes a 45-year-old man with an abnormal origin of the right ventricular branch of the right coronary artery originating from a separate ostium in the right coronary sinus. Coronary arteries with abnormal origin constitute roughly 0.64% to 1.2% of all the representations encountered during coronary angiography. We suggest that the presence of such a vessel must be shown in patients undergoing coronary angiography and/or cardiac surgery.
