Anterior Descending Branch of Left Coronary Artery

Wednesday, July 15, 2015

The anterior descending branch of left coronary artery is one of the two main branches into which the left coronary artery of the heart divides, the other being the circumflex artery. At first, it has a brief winding course around the base of the pulmonary artery; then, it runs down almost vertically across the myocardium, along the anterior intraventricular sulcus, extending to the apex of the heart and projecting lateral diagonal branches. Function: the anterior descending branch of left coronary supplies the anterolateral aspect of myocardium, specially the left ventricle walls, and the interventricular septum. The clinical importance of this oxygen-rich blood vessel is that it is the most frequently occluded artery of all the branches of the coronary arteries.
