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. It supplies the anterior portion of the left ventricle.[1] It provides about half of the arterial supply to the left ventricle and is thus considered the most important vessel supplying the left ventricle.[citation needed] Blockage of this artery is often called the widow-maker infarction due to a high risk of death.[2]
