Figure 3 Variability in the coronary artery blood supply to the myocardium. Three-dimensional volume-rendered electrocardiogram-gated cardiac computed tomography images showing the inferior surface of the heart representing different coronary anatomy variants; A: Standard, right-dominant circulation. Right coronary artery (RCA) supplies posterior descending branch (arrow). Left circumflex coronary artery (LCX) supplies only inferolateral left ventricular myocardium; B: Left-dominant circulation. LCX supplies posterior descending branch (arrow). RCA supplies only right ventricular myocardium; C: Codominant circulation. Inferior myocardium is supplied both RCA and LCX.
