text: Within millimeters after emerging from the aorta, the right coronary artery gives off two branches: 1) the conus (arteriosus) artery which runs to the right ventricular outflow tract, and 2) the atrial branch which gives off the SA nodal artery (in ~ 50-73% of hearts), which runs along the anterior right atrium to the superior vena cava, encircling it before reaching the SA node.
