Successful percutaneous coronary intervention for severe stenosis of a double right coronary artery.

Anomalies of the coronary arteries are uncommon and often asymptomatic. Double right coronary artery (RCA) is a very rare coronary anomaly. So far, the number of reported cases of double RCA is low. We describe a case of a 50-year-old female patient hospitalised with the diagnosis of unstable angina pectoris. RCA injection showed filling of two separately originating RCA, coursing towards the right atrioventricular groove. Coronary angioplasty was successful.
