Middle cardiac vein
Middle Cardiac Vein
The Middle Cardiac Vein (pronunciation: /ˈmɪdəl kɑːrˈdiæk veɪn/), also known as the posterior interventricular vein, is a blood vessel that carries deoxygenated blood from the heart muscle back to the heart.
Etymology
The term "Middle Cardiac Vein" is derived from the Latin words 'medius' meaning middle, 'cardia' meaning heart, and 'vena' meaning vein.
Anatomy
The Middle Cardiac Vein begins at the apex and ascends in the posterior longitudinal sulcus to the base of the heart. It drains the areas supplied by the right coronary artery and the posterior descending artery. It empties into the coronary sinus, which then drains into the right atrium of the heart.
