The<unk>  coronary artery (RCA) is a coronary artery with a single origin near the<unk>  semilunar cusp of the aortic valve that bifurcates (branches) to supply the<unk>  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 left ventricle via the<unk>  posterolateral branch.  On coronary angiography, the RCA is easily recognizable as it appears like the letter C in the left anterior oblique (LAO) projection and appears like a letter L in the<unk>  anterior oblique (RAO) projection.  There are three angiographic views of the RCA that are traditionally obtained to visualize the proximal, middle, and distal segments.
