title: Anomalous origin of the anterior descending coronary artery from a non-dominant right coronary artery.
abstract: We present a patient with rheumatic mitral valve disease with anomalous origin of the anterior descending coronary artery. The coronary anatomy was unusual for two reasons; firstly, the anterior descending coronary artery was a branch of a non-dominant right coronary artery, and secondly it passed to the left in the interventricular septum beneath the right ventricular infundibulum. As far as we are aware, this anatomical variation has not been described before and it appears to be of no haemodynamic significance.
