In type IV dual left anterior descending (LAD) coronary artery, one short LAD artery originates from the left main coronary artery and the second long LAD takes origin from the right coronary sinus or right coronary artery (RCA) with an independent distal anterior interventricular sulcus course. Here, we describe a patient with a variant of Type IV dual LAD wherein the first LAD originated from the left main coronary artery but was long (instead of a usual short one) and the second LAD did not have an independent distal anterior interventricular sulcus course. It originated from proximal RCA coursing with a retro-aortic loop and continuing at mid-segment of the first LAD without independent course.
