Middle cardiac vein

Middle cardiac vein
Base and diaphragmatic surface of heart. (Middle cardiac vein labeled at bottom.)
ARTERIES: RCA = right coronary AB = atrial branches SANB = sinuatrial nodal RMA = right marginal LCA = left coronary CB = circumflex branch LAD/AIB = anterior interventricular LMA = left marginal PIA/PDA = posterior descending AVN = atrioventricular nodal VEINS: SCV = small cardiac ACV = anterior cardiac AIV/GCV = great cardiac MCV = middle cardiac CS = coronary sinus

Anatomical terminology [edit on Wikidata]

The middle cardiac vein commences at the apex of the heart. It passes posteriorly along the inferior interventricular sulcus to end at the coronary sinus near the sinus' termination.^[1]

Structure

The middle cardiac vein commences at the cardiac apex (here, it is contiguous with the great cardiac vein, thus forming - along with the coronary sinus - a complete venous circle).^[1]

The middle cardiac vein has a constant location on the surface of the ventricles.^[2]

The middle cardiac vein is useful for epicardial access to the inferior side of the ventricles.^[3]
