This occurs when plaques (made up of deposits of cholesterol and other substances) build up over time in the walls of the arteries. Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart ...
The presence or absence of atherosclerosis or atheroma within the walls of the arteries cannot be clearly determined. Coronary angiography can visualize coronary artery stenosis, or narrowing of the blood vessel. The degree of stenosis can be determined by comparing the width of the lumen of narrowed segments of blood vessel with wider segments ...
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 ...
Corrections of arrows of external iliac artery. Add muscular branches from deep femoral artery (after deleted an inexistent medial artery). 17:10, 22 June 2020: 550 × 830 (1.18 MB) Jmarchn: Add label for gastroduodenal artery. Better draw for epigastric arteries. Added temporal arteries (not labeled). 11:01, 21 June 2020: 550 × 830 (1.19 MB ...
The left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum. The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery.

[citation needed] The left coronary artery typically runs for 10–25 mm, then bifurcates into the left anterior descending artery, and the left circumflex artery. [ 1 ] The part that is between the aorta and the bifurcation only is known as the left main artery (LM), while the term "LCA" might refer to just the left main, or to the left main ...
