Small cardiac vein

Vein: Small cardiac vein
Base and diaphragmatic surface of heart.
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
Latin	vena cordis parva
Gray's	subject #166 642
Drains to	coronary sinus

The small cardiac vein (right coronary vein or vena cardiaca parva) runs in the coronary sulcus between the right atrium and ventricle, and opens into the right extremity of the coronary sinus.

It receives blood from the back of the right atrium and ventricle; the right marginal vein ascends along the right margin of the heart and joins it in the coronary sulcus, or opens directly into the right atrium.
