- Flow and wall shear stress in end-to-side and side-to-side anastomosis of venous coronary artery bypass grafts

..................................................

Figure 1.Models. Anatomical depiction of the two models including the aortocoronary bypasses (arrows), the coronary arteries (arrowheads), the anastomoses (asterisks) and their relation to the heart and the aorta.

..................................................

Figure 2.Input functions. Flow velocities throughout one cardiac cycle used as input functions at the ostium of the left main artery (LMA), right coronary artery (RCA), and the coronary artery bypass graft.

..................................................

Figure 3.Flux in end-to-side anastomosis. Integrated volumetric flux (ml/sec) at indicated cross-sections (cuts) in the RCA and the end-to-side anastomosis.

..................................................

Figure 4.Velocity and shear stress in end-to-side anastomosis. Velocity-coded streamlines (m/sec) and wall shear stress (Pa) in an end-to-side anastomosis at three different time steps of the cardiac cycle.

..................................................

Figure 5.Shear stress distribution in end-to-side anastomosis. Color-coded wall shear stress (Pa) and corresponding values plotted against the distance (mm) from the green to the red point at timestep 20 on three different paths upon the walls of the end-to-side anastomosis.

Figure 6.Flux in side-to-side anastomosis. Integrated volumetric flux (ml/sec) at indicated cross-sections (cuts) in the LAD and the side-to-side anastomosis

..................................................

Figure 7.Velocity and shear-stress in side-to-side anastomosis. Velocity-coded streamlines (m/sec) and wall shear stress (Pa) in a side-to-side anastomosis at three different time steps of the cardiac cycle.

..................................................

Figure 8.Shear stress distribution in side-to-side anastomosis. Color-coded wall shear stress (Pa) and corresponding values plotted against the distance (mm) from the green to the red point at timestep 20 on four different paths upon the walls of the side-to-side anastomosis.
