Collateral circulation to the diagonal artery from the infundibular coronary artery in obstructive coronary arterial disease.
We report an unusual collateral pathway from the isolated infundibular (third coronary) artery to the diagonal artery in a young adult male with a history of recent anteroseptal myocardial infarction and apparently angiographically normal left and right coronary arteries. The isolated infundibular (conus) artery is an important source of collateral pathways in obstructive coronary arterial disease. Its selective arteriography is essential for complete angiographic evaluation of these patients.
