The Right Coronary System

The heart specimen has been injected with barium into the coronary arteries and in this instance the right coronary artery is demonstrated. In image (b), the RCA is deep and hidden and the red overlay represents the expected position of the proximal RCA in the anterior part of the A-V groove. Image (c) shows the conal artery or the artery of Vieussens supplying the right ventricular outflow tract. The specimen shows many branches in (d) that supply the anterior wall of the RV but the only named vessel is the acute marginal artery (arrow) that travels along the right lateral aspect of the right ventricle (white arrow).
