Artery: Posterior interventricular artery
Base and diaphragmatic surface of heart. (Posterior descending artery not visible, but it runs near the middle cardiac vein, which is labeled at the 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
Latin	ramus interventricularis posterior arteriae coronariae dextrae
Gray's	subject #142 547
Supplies	ventricles interventricular septum
Source	right coronary artery
Vein	middle cardiac vein, posterior interventricular vein

The posterior interventricular artery (PIV) (or posterior descending artery (PDA)) is an artery running in the posterior interventricular sulcus to the apex of the heart where it meets with the anterior interventricular artery. It supplies the posterior 1/3rd of the interventricular septum. The remaining anterior 2/3rds is supplied by the anterior interventricular artery which is a septal branch of the left anterior descending artery, which is a branch of left coronary artery.

It is typically a branch of the right coronary artery (70%, known as right dominance). Alternately, the PIV can be a branch of the circumflex coronary artery (10%, known as left dominance) which itself is a branch of the left coronary artery. It can also be supplied by an anastomosis of the left and right coronary artery (20%, known as co-dominance).

Variants have been reported.
