Location: The left coronary artery (left main coronary artery) emerges from the aorta through the ostia of the left aortic cusp, within the sinus of Valsalva. The plane of the semilunar valve is tilted so that the ostium of the left coronary artery is superior and posterior to the right coronary ostium.The left coronary artery travels from the aorta, and passes between the pulmonary trunk and the left atrial appendage.Under the appendage, the artery divides (and is thus a very short vessel) into the anterior interventricular (left anterior descending artery) and the left circumflex artery.he plane of the semilunar valve is tilted so that the ostium of the left coronary artery is superior and posterior to the right coronary ostium. The left coronary artery travels from the aorta, and passes between the pulmonary trunk and the left atrial appendage.
