anterior interventricular sulcus

[TA]
a groove on the anterosuperior surface of the heart, marking the location of the septum between the two ventricles.

Short LAD runs in the anterior interventricular groove, giving rise to septal perforator and ends in the proximal anterior interventricular groove.
The long LAD also runs in the anterior interventricular groove, descends on the left ventricular side of it, giving rise to LV diagonals, and then reenters the distal anterior interventricular groove down till apex.
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.
Short LAD travels along the proximal part of the anterior interventricular groove but stops well short of the apex (short LAD), long LAD artery joins the anterior interventricular groove distally and reaches the apex after originating elsewhere (long LAD) as shown in fig-3.
The LAD courses downward in the anterior interventricular groove towards the cardiac apex.
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.
(4) The LAD courses through the anterior interventricular groove and provides diagonal branches to the anterior left ventricle and septal branches to the anterior interventricular septum.
This anomaly refers to 2 LAD arteries: one short LAD, which terminates in the anterior interventricular groove without reaching the apex, and one long LAD, which originates from the LAD proper or anomalously from the RCA/opposite sinus, enters the distal anterior interventricular groove, and terminates at the apex.
Similar to the previous cases, (3) the left anterior descending artery had a prominent intramural course within the ventricular septum prior to emerging in the anterior interventricular groove.
