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 nodi atrioventricularis

The atrioventricular nodal branch most frequently arises as a distal branch from the right coronary artery, but occasionally the atrioventricular node receives blood from the circumflex branch of the left coronary artery.
