Right Coronary Artery

ScienceDirect image

The right coronary artery (RCA) is initially imaged in the LAO 30-degree view, which displays the proximal and distal RCA well, and the artery appears as the letter C. To evaluate the right posterior descending artery (rPDA) and posterior lateral branches (rPL), RAO 0-degree, cranial 30-degree view is utilized.
