Anomalous Origin of the Stenosed Circumflex Artery from the Right Coronary Artery

We report a case of anomalous origin of the stenosed circumflex artery from the right coronary artery. The patient was operated upon successfully, and the right internal mammary artery was placed on the circumflex artery.
