how many coronary arteries are coming off of the root of the aorta?
right coronary artery
coronary arteries supply blood to the myocardium and other components of the heart. two coronary arteries originate from the left side of the heart at the beginning (root) of the aorta, just after the aorta exits the left ventricle. there are three aortic sinuses (dilations) in the wall of the aorta just superior to the aortic semilunar valve. two of these, the left posterior aortic sinus and anterior aortic sinus, give rise to the left and right coronary arteries, respectively. the third sinus, the right posterior aortic sinus, typically does not give rise to a vessel. coronary vessel branches that remain on the surface of the artery and follow the sulci of the heart are called "epicardial" coronary arteries.
coronary circulation
coronary arteries are examined closely, and the ostia and proximal arterial course are identified, as are any infundibular branches, if they exist. the coronary ostia and a large "button" of surrounding aortic wall are then excised from the aorta, well into the sinus of valsalva; and the proximal sections of the coronary arteries are separated from the surface of the heart, which prevents tension or distortion after anastomosis to the neo-aorta. infundibular branches are sometimes unable to be spared, but this is a very rare occurrence. if the aortic commissure has not previously been marked, the excised coronary arteries will be used to determine the implantation position of the aorta.
