Right coronary artery: Anatomy, branches, supply - Kenhub
Oct 30, 2023 · The right coronary artery (RCA) is one of two main coronary vessels that supply the myocardium (the other being the left coronary artery). It originates from the right aortic sinus of the ascending aorta and runs in the right part of atrioventricular groove ( coronary sulcus ) wrapping around the right side of the heart .

Sep 6, 2024 · The three segments of the right coronary artery are: proximal segment: from the right coronary artery origin to halfway along the acute margin of the heart. mid segment: from halfway along the acute margin to the acute angle of the heart, where it courses along the posterior AV groove. distal segment: from the acute angle to the apex. Branches
Right coronary artery - Wikipedia
In the blood supply of the heart, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. [1] [2] It travels down the right coronary sulcus, towards the crux of the heart.
Anatomy and Function of the Coronary Arteries
Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm. The right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery.
Right Coronary Artery | Complete Anatomy - Elsevier
The right coronary artery supplies almost the entire right ventricle, as well as the right atrium and a portion of the left atrium. It supplies the posterior one third of the interventricular septum. It also contributes to the supply of the conduction system, including the sinuatrial node and the atrioventricular node.
Coronary angiography right coronary artery - wikidoc
The right coronary artery (RCA) is a coronary artery with a single origin near the right semilunar cusp of the aortic valve that bifurcates (branches) to supply the right ventricular free wall through the acute marginal branches), the inferior wall of the left ventricle through the posterior descending artery, and the posterolateral wall of the ...
Right coronary artery - wikidoc
The right coronary artery (RCA) originates above the right cusp of the aortic valve. It travels down the right atrioventricular groove , towards the crux of the heart . In addition to supplying blood to the right ventricle (RV), the RCA supplies 25% to 35% of the left ventricle (LV).
Anatomy, Thorax, Heart Right Coronary Arteries - StatPearls
Jul 24, 2023 · The right coronary artery finds its origin from the aorta immediately above the right (coronary) semilunar cusp of the aortic valve. It follows a course between the pulmonary trunk and right atrium in the right atrioventricular groove and curves around the acute angle of the heart.
Right coronary artery - e-Anatomy - IMAIOS
The right coronary artery (RCA) originates from the right coronary sinus and travels in the coronary sulcus (atrioventricular groove) between the right atrium and ventricle. It gives rise to several branches, including the conal branch, the sinus node artery, and the inferior interventricular artery (posterior descending artery (PDA)). Theinferior interventricular artery, which supplies the ...
Is right ventricular free wall revascularization underrated?
Jul 24, 2023 · A number of patients present with extensive right coronary artery (RCA) disease, for which bypassing distal branches alone does not address RV free wall ischemia. Without adequate collateralization between the right and left coronary systems, ignoring RV free wall ischemia can be a cause of early RV dysfunction, as in the case presented here.
