What two arteries does the right coronary artery branch into?

The right coronary artery (RCA) primarily supplies blood to the right side of the heart and it typically branches into several important arteries. Among those, the PDA, which stands for posterior descending artery, is one of its main branches. The PDA runs along the posterior interventricular sulcus and supplies blood to the inferior wall of the heart, particularly the inferior part of the left ventricle and the interventricular septum.

In addition to the PDA, the RCA gives rise to acute marginal branches. These branches are significant because they serve the right ventricle. The acute marginal branches arise as the RCA approaches the right margin of the heart and further ensures that the right ventricle receives adequate perfusion.

The understanding of these branches is crucial for cardiac imaging and interventions, as well as for interpreting various cardiac conditions that may arise depending on the perfusion of these specific regions of the heart.
