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.
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.
