Overview
LAD Description
LAD Segments
The LAD can be divided into three main segments which are:
Proximal left anterior descending artery
It extends from the bifurcation of the left main coronary artery to the origin of the first septal artery.
Mid left anterior descending artery
It extends from the origin of the first septal artery to the origin of the third septal artery.
Distal left anterior descending artery
It extends from the origin of the third septal artery to the apex of the left ventricle. If there is no third septal branch, then the third segment begins halfway between S1 and the apex of the left ventricle.
