A 70-year-old man presented with a 6-month history of exercise-induced angina pectoris and gave a history of myocardial infarction occurring 31 years previously. Left ventricular angiography showed normal contractility. Selective coronary arteriography demonstrated proximal occlusion of both the non-dominant right (RCA) and the left anterior descending (LAD) coronary arteries with severe stenoses in the left circumflex coronary artery (fig 1). Left ventricular function had been preserved by the existence of a large conus artery collateral (fig 1, arrows) communicating between the proximal RCA (proximal to its occlusion point; fig 1, open arrow) and the LAD beyond its occlusion point (fig 1, open and curved arrow).
