Proximal LAD artery
Proximal LAD artery
- Acronym: pLAD
Definition
The proximal left anterior descending (LAD) is defined as the segment extending from the bifurcation of the LMCA to the first major septal perforator branch (some definitions say to first diagonal).
The proximal left anterior descending (LAD) artery originates from the left main coronary artery (LMCA) shortly after the LMCA bifurcates from the left coronary sinus. The LAD then courses along the anterior interventricular groove towards the apex of the heart.
The proximal LAD gives rise to several important branches, including the left conus artery, septal perforators, and diagonal branches. These branches supply blood to the anterior wall of the left ventricle and the anterior two-thirds of the interventricular septum.[3]
