Coronary sulcus

The coronary sulcus, also known as the atrioventricular groove, is a groove that separates the atria and ventricles of the heart. It extends from the upper medial end of the third left costal cartilage to the middle of the right sixth chondrosternal joint.

The coronary sulcus hosts several important coronary vessels including the coronary sinus, right coronary artery and left coronary artery. The coronary sinus is located in the posterior portion of the coronary sulcus on the diaphragmatic (inferior) surface of the heart. The sinus serves as the primary collector of cardiac venous blood. 

Along with the posterior interventricular sulcus, the coronary sulcus makes the crux of the heart or crux cordis.
