Numbering scheme for coronary artery segments: 1 = proximal RCA; 2 = middle RCA; 3 = distal RCA; 4 = combined posterior descending and posterolateral branches of RCA; 5 = LM; 6 = proximal LAD; 7 = middle LAD; 8 = distal LAD; 9 = first diagonal LAD; 10 = second diagonal LAD; 11 = proximal LCX; 12 = distal LCX; 13 = first marginal branch of LCX.
