The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body.
The catheter is threaded into an artery in the forearm, and the tip is advanced through the arterial system into the major coronary artery. X-ray images of the transient radiocontrast distribution within the blood flowing inside the coronary arteries allows visualization of the size of the artery openings .

The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
Cast of coronary arteries (right = yellow, left = red) There are some anastomoses between branches of the two coronary arteries. However the coronary arteries are functionally end arteries and so these meetings are referred to as potential anastomoses, which lack function, as opposed to true anastomoses like that in the palm of the hand. This ...

The circumflex artery supplies the posterolateral left ventricle and the anterolateral papillary muscle. It also supplies the sinoatrial nodal artery in 38% of people. It supplies 15–25% of the left ventricle in right-dominant systems. If the coronary anatomy is left-dominant, the circumflex artery supplies 40–50% of the left ventricle.
The right coronary artery supplies oxygenated blood to the right atrium, the right ventricle, and the posterior third and inferior end of the interventricular septum. [2] [5] It may also supply 25% to 35% of the left ventricle (LV). [10] There is significant overlap of supply of the coronary arteries. [2]
