Anomalies of the coronary artery are often asymptomatic and uncommon. We report an extremely rare coronary artery anomaly, a double right coronary artery. A 50-year-old male patient was hospitalized with the diagnosis of unstable angina pectoris. Right coronary artery (RCA) injection showed filling of two separately originating RCAs, coursing towards the right atrio-ventricular groove. Then they give a marginal branch and a septal artery, terminated by giving off the posterior descending artery (PDA) in posterior interventricular groove. Coronary anomalies should be recognized to avoid problems during coronary intervention and cardiac surgery.
