TERMINOLOGY
Abbreviations
- Coronary arteries and their branches
- Left main (LM) coronary artery
- Left anterior descending (LAD) coronary artery
- Proximal, mid, and distal LAD (pLAD, mLAD, dLAD)
- Diagonal branches: D1, D2, D3, etc.
- Ramus intermedius (RI)
- Left circumflex (LCX)
- Proximal and mid/distal LCX (pCx, LCX)
- Obtuse marginal branches: OM1, OM2, OM3, etc.
- Posterior lateral branch (PLB)
- Posterior left ventricular (PLV) branch
- Posterior descending artery (PDA)
- Right coronary artery (RCA)
- Proximal, mid, and distal RCA (pRCA, mRCA, dRCA)
- Acute marginal (AM) branch
- Sinoatrial node (SAN) branch
- Atrioventricular node (AVN) branch
- Grafts
- Saphenous vein graft (SVG)
- Coronary artery bypass graft (CABG)
- Left internal mammary artery (LIMA)
- Right internal mammary artery (RIMA)
- Alternative international nomenclature
- Ramus interventricularis anterior (RIVA) = LAD
- Ramus circumflexus (RCx) = LCX
- Ramus interventricularis posterior (RIVP, RIP) = PDA
- Ramus marginalis (RM or M) = OM
- Right posterolateral branch (RPL) = PLV branch from RCA
- Ramus posterolateralis dexter (RPD) = PLV branch from RCA; careful not to confuse with abbreviation for right posterior descending artery
- Right posterior descending artery (RPD) = PDA from RCA
- Coronary arteries and their branches
Synonyms
- Epicardial arteries
