The left anterior descending (LAD) artery also known as the anterior inter ventricular branch of the left coronary artery is a branch or continuation of the left coronary artery and supplies the anterolateral myocardium and apex and with one of its branches supplying the anterior 2/3 of the interventricular septum.

Gross Anatomy

anatomy

The left anterior descending artery (LAD) has one main source and gives off several branches. It can be divided into proximal, mid and distal segments and this helps to differentiate the names of its various small branches ¹:

source: left coronary atery
branches: septal perforators and diagonal branches¹

Relations

The LAD lies in the anterior epicardial ventricular septum ^1:

inferior: myocardium
superior: pericardium

Variant Anatomyanatomy

dual left anterior descending coronary artery ²: it describes two left anterior descending coronary ateries, one usually shorter in length that are both situated in the anterior inter ventricular groove. It is important to know of this variation when planning surgical vascularisation ³.
