It courses in the anterior interventricular groove down towards the apex and gives off septal perforators to the interventricular septum and diagonal branches to the anterior wall of the left ventricle.
At a rough definition, dual LAD consist of a short LAD which terminates high in the anterior interventricular groove mainly supplying the septal wall, and a long LAD which re-enters the anterior interventricular groove at the distal part, supplying the free wall and the apical wall of the left ventricle.
(3,6) For example, a subepicardial artery that courses through the anterior interventricular groove and provides septal branches is termed the LAD, regardless of its origin from the aorta.
Ferreira et al divided the intramuscular LAD into 2 types: the superficial type, in which the intramuscular segment runs on the interventricular groove, and the deep type, in which the intramuscular segment deviates toward the right ventricle and is crossed by a muscle bundle arising from the right ventricle4.
