origin, right aortic sinus; distribution, it passes around the right side of the heart in the coronary sulcus, giving branches to the right atrium and ventricle, including the atrioventricular branches, the sinuatrial nodal branch, the right marginal artery, the atrioventricular nodal branch, and the posterior interventricular branch.

right coronary artery

one of a pair of branches of the ascending aorta, arising in the right posterior aortic sinus, passing along the right side of the coronary sulcus, and dividing into the right interventricular artery and a large marginal branch. It supplies both ventricles, the right atrium, and the sinoatrial node. Compare left coronary artery.

right coronary artery

Abbreviation: RCA
One of the two main epicardial arteries that feed the heart muscle. It originates from the right aortic sinus, a dilation in the aorta just behind one of the leaflets of the aortic valve. It runs to the right along the outside of the heart in the atrioventricular groove, i.e., the coronary sulcus, between the atria and the ventricles. Usually, its two main branches are the right marginal artery and the posterior descending artery. Among the heart regions it supplies are the sinoatrial (SA) and atrioventricular (AV) nodes, the right ventricle, the right atrium, and often, the inferior or posterior wall of the left ventricle.
Synonym: right main coronary artery See: aorta (Branches of aorta) and heart (The heart) for illus.
