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.
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.
Myocardial bridges are mostly seen on mid segment of left anterior descending artery, which routes within interventricular groove (9).
It gave the left anterior descending artery (LAD) coursing to the interventricular groove and left circumflex artery (CxA) coursing to the left atrioventricular groove.
