title: A case of type IV dual left anterior descending artery associated with anomalous origin of the left circumflex artery in the presence of coronary atherosclerosis.
abstract: Double origin of the left anterior descending coronary artery (LAD) from the left and right coronary arteries (type IV dual LAD) is a rare coronary anomaly. We report an unusual case of type IV dual LAD associated with anomalous origin of the left circumflex artery from the right coronary artery in a patient with a recent history of myocardial infarction. The first diagonal branch originating from the short LAD demonstrated 70-80% stenosis and the posterior descending artery was totally occluded. We believe that this unusual variance of the coronary arteries in association with atherosclerosis has not been previously reported.
