The atrioventricular sulcus or groove is where the right coronary artery lies. It is between the right atrium and the right ventricle.
the right interventricular sulcus I think it is atrioventricular sulus
Coronary sulcus
The Coronary Sinus
Anterior and posterior interventricular/longitudinal sulci (singular sulcus).
