left anterior descending artery









































the left anterior descending artery (also lad, anterior interventricular branch of left coronary artery, or anterior descending branch) is a branch of the left coronary artery. occlusion of this artery is often called the "widow-maker infarction" due to a high death risk.

it passes at first behind the pulmonary artery and then comes forward between that vessel and the left atrium to reach the anterior interventricular sulcus, along which it descends to the notch of cardiac apex.
left anterior descending artery
heart tissue receives blood from two arteries which arise just above the aortic valve. these are the left main coronary artery and the right coronary artery. the left main coronary artery splits shortly after leaving the aorta into two vessels, the left anterior descending and the left circumflex artery. the left anterior descending artery supplies heart tissue and the front, outer side, and the septum of the left ventricle. it does this by branching into smaller arteries—diagonal and septal branches. the left circumflex supplies the back and underneath of the left ventricle. the right coronary artery supplies the right atrium, right ventricle, and lower posterior sections of the left ventricle. the right coronary artery also supplies blood to the atrioventricular node (in about 90% of people) and the sinoatrial node (in about 60% of people). the right coronary artery runs in a groove at the back of the heart and the left anterior descending artery runs in a groove at the front. there is significant variation between people in the anatomy of the arteries that supply the heart the arteries divide at their furtherst reaches into smaller branches that join together at the edges of each arterial distribution.
