Figure 4 Three-Dimensional Reconstructions Showing the Anatomical Variability of the Relationships Between the Vascular Structures in the Atrioventricular Groove, and the Close Relationship Between the CS–GCV and the Left Atrial Wall
(A) Three-dimensional reconstruction (anterior view) showing the position of the CS–GCV and of the LCX, which makes a U-turn around the CS–GCV (U). (B) Three-dimensional reconstruction (posterior view) showing the position of the CS–GCV, which is adjacent to the left atrial wall rather than the MVA. The coronary arteries have been removed for better visualization of the atrioventricular groove. PIV = posterior interventricular vein; other abbreviations as in Figures 1 and 3.
