Cardiac Artery Anatomy

The right coronary artery runs in a groove at the back of the heart and the left anterior descending artery runs in a groove at the front. Coronary artery disease coronary artery disease or coronary heart disease chd is a leading cause of death both in the uk and worldwide.

Each artery is a muscular tube lined by smooth tissue and has three layers.

Cardiac artery anatomy. It describes a reduction in blood flow to the myocardium and has several causes and consequences. The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. These arteries divide into progressively smaller branches.

The left main coronary artery has a short common trajectory branching into the left anterior descending artery and the circumflex artery. These two branches subdivide and course over the surface of the heart epicardium as they traverse away from the aorta. The intima the inner layer lined by a smooth tissue called endothelium.

It passes between the right auricle and the pulmonary trunk in the atrioventricular groove. Normal coronary anatomy the coronary arteries arise from the aortic sinuses converging towards the apex of the heart. This is why the coronary system is usually considered a system with three major arteries the left anterior descending artery the circumflex artery and the right coronary artery.

There is significant variation between people in the anatomy of the arteries that supply the heart the arteries divide at their furtherst reaches into smaller branches that join together at the edges of each. Right coronary artery rca. Normally one or more marginal arteries arise from the right coronary artery inferior to the right atrium.

The adventitia connective tissue anchoring arteries to nearby tissues. The media a layer of muscle that lets arteries handle the high pressures from the heart. This artery supplies blood to the outer side and back of the heart.

The right coronary artery proceeds along the coronary sulcus and distributes blood to the right atrium portions of both ventricles and the heart conduction system. The circumflex artery branches off the left coronary artery and encircles the heart muscle. The right coronary artery proceeds along the coronary sulcus and distributes blood to the right atrium portions of both ventricles and the heart conduction system.

Normally one or more marginal arteries arise from the right coronary artery inferior to the right atrium. The coronary arteries originate as the right and left main coronary arteries which exit the ascending aorta just above the aortic valve coronary ostia. It passes between the right auricle and the pulmonary trunk in the atrioventricular groove.

The marginal arteries supply blood to the superficial portions of the right ventricle. The right coronary artery arises from the anterior aortic sinus at the beginning of the ascending aorta.
