Coronary sulcus
Groove on the surface of the heart that separates the atria from the ventricles / From Wikipedia, the free encyclopedia
The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart at the base of right auricle that separates the atria from the ventricles.[1][2] The structure contains the trunks of the nutrient vessels of the heart,[2] and is deficient in front, where it is crossed by the root of the pulmonary trunk. On the posterior surface of the heart, the coronary sulcus contains the coronary sinus.[3] The right coronary artery, circumflex branch of left coronary artery, and small cardiac vein all travel along parts of the coronary sulcus.
