Middle cardiac vein

The Middle Cardiac Vein (MCV), also known as the posterior interventricular vein, is a blood vessel that carries deoxygenated blood from the heart back to the heart. It is located in the posterior part of the heart, running along the posterior interventricular sulcus.

Anatomy

The Middle Cardiac Vein begins at the apex of the heart, where it is continuous with the anterior interventricular artery. It runs in the posterior interventricular sulcus, towards the base of the heart. Here, it drains into the coronary sinus, which in turn empties into the right atrium.

Function

The primary function of the Middle Cardiac Vein is to carry deoxygenated blood from the myocardium of the heart back to the heart itself. This is part of the coronary circulation, which is responsible for supplying the heart with oxygen and nutrients, and removing waste products.

Clinical Significance

The Middle Cardiac Vein is an important structure in the diagnosis and treatment of heart diseases. It can be visualized using coronary angiography, which can help identify blockages in the coronary circulation. In addition, it can be used as a route for the delivery of medications or devices in the treatment of heart diseases.
