The coronary groove is a deep depression on the surface of the heart between the ventricles and atria. It is located in the center of the heart and is about 2 cm long. This groove contains important structures such as the right coronary artery, vein, periarterial nerve and lymphatic vessels.

The coronary sulcus is an important anatomical structure as it provides blood supply and nutrition to the heart. The right coronary artery passes through this groove, providing blood supply to the myocardium of the left ventricle. Also in this groove is the venous sinus - the place where blood from the heart collects. Periarterial nerve plexuses in the coronary sulcus provide innervation to the heart, and lymphatic vessels drain excess fluid from the heart.

In addition, the coronary sulcus has important clinical significance. For example, during myocardial infarction, when the blood supply to the heart is disrupted, necrosis of the heart muscle can occur, which can lead to rupture of the heart wall and the development of cardiac tamponade. In this case, cardiac rupture may be associated with damage to the periarterial nerve plexus or lymphatic vessels located in the coronary groove.

Thus, the coronary groove is an important anatomical formation that plays a key role in the functioning of the heart and its blood supply. Knowledge of its location and structure can help in the diagnosis and treatment of various heart diseases.

The coronary groove is one of the most important and complex structures in the anatomy of the heart. It is an important anatomical feature that determines and influences the functioning of the heart and blood circulation in the body. The coronary groove is located on the surface of the right ventricle of the heart in the depression between the atrium
