Why is a heart attack that afflicts the left coronary artery called the "widowmaker"? The coronary arteries are the sole suppliers of clean arterial blood to the heart muscle itself. They deliver 200 -250 mL of blood to the myocardium per minute at rest.The left coronary artery carries about 85% of the blood supply to the heart, while the right coronary artery carries the remainder. The coronary arteries begin just above the aortic valve where the aorta exits the heart. The left main coronary artery supplies the left ventricle, interventricular septum, and parts of the right ventricle. The two main branches are the left anterior descending and the circumflex arteries. The right coronary artery supplies the right atrium & right ventricle. It supplies a small part of the left ventricle and the conduction system. It's two main branches are the right anterior descending and the marginal branch. In addition to the two main arteries many smaller connections between arterioles provides back-up circulation.
