Overview

The left main coronary artery is the origin of the left coronary artery that lies between the aorta and the bifurcation of the left coronary artery into the left anterior descending artery and the left circumflex artery. It is 1 to 25 mm long, and is normally 3 to 5 mm wide. Severe narrowing of the left main coronary artery can result in death due to coronary ischemia, and is an indication for coronary artery bypass grafting or coronary stenting.
