All coronary physiology serves a single purpose: the capacity to achieve extraordinary myocardial blood flow and cardiac output for extreme physical demands.

The heart is highly metabolically active and boasts the highest oxygen consumption by mass of any organ. This demand for oxygen is met by the coronary circulation, which is responsible for delivering blood to the myocardium and represents approximately 5% of cardiac output. What is collateral circulation? Collateral circulation is a network of tiny blood vessels, and, under normal conditions, not open. When the coronary arteries narrow to the point that blood flow to the heart muscle is limited (coronary artery disease), collateral vessels may enlarge and become active. Right dominant circulation was found in 77% of the patients, while 15% of subjects had co dominant and 8% left dominant circulation.

The vessels that supply blood high in oxygen to the heart are known as coronary Se hela listan på embryology.med.unsw.edu.au Coronary Dominance. Coronary dominance refers to which vessel gives rise to the PDA: In a right-dominant circulation the PDA is supplied by the RCA; In a left-dominant circulation the PDA is supplied by the LCx; Additionally: The SA node is supplied by the RCA in 60% of individuals; The AV node is supplied by the RCA in 90% of individuals; Venous Anatomy 2018-04-22 · Coronary Circulation. DEFINITION: The coronary circulation supplies 250mL/min (5% of cardiac output) of oxygenated blood to the heart. Right and left coronary arteries arise from two aortic sinuses within the aortic root. The arteries divide and their branches supply oxygenated blood to specific structures within the heart. 2006-03-22 · Fractale structure of the coronary circulation (Gould, Finet) X 1 X 0.75 X 4.5 X 10.5 X 90 X 1100 epicardial compartment (> 400 µm) microvascular compartment traditionally visible by angiography and more recently by many invasive and non-invasive imaging methods The major vessels of the coronary circulation are the left main coronary that divides into left anterior descending and circumflex branches, and the right main coronary artery.

The blood inside the atria and ventricles does not directly support the heart muscle; the heart has to deliver and drain blood as it does for any other muscle. However, these arteries and veins represent a site-specific network. Circulation. 2019; 139:e891–e908.
