Great cardiac vein

Great Cardiac Vein

The Great Cardiac Vein (GCV) is a blood vessel that carries deoxygenated blood from the heart muscle back to the heart. It is one of the main veins in the coronary circulation, which is the circulation of blood in the blood vessels of the heart muscle (myocardium).

Anatomy

The Great Cardiac Vein begins at the top of the anterior interventricular sulcus and runs along the anterior interventricular groove. It then curves around the left side of the heart, running in the coronary sulcus. It drains into the coronary sinus on the posterior aspect of the heart.

Function

The primary function of the Great Cardiac Vein is to drain the blood from the area of the heart it covers, mainly the left and right ventricles and the left atrium. It carries deoxygenated blood, which is blood that has delivered its oxygen to the heart muscle, back to the heart.

Clinical Significance

The Great Cardiac Vein is an important structure in cardiac procedures such as coronary angiography and coronary artery bypass grafting (CABG). It is also significant in conditions such as coronary artery disease (CAD) and myocardial infarction (heart attack), where blockages in the coronary circulation can lead to heart muscle damage.
