3D Simulation Analysis of Central Shunt in Patient-Specific Hemodynamics: Effects of Varying Degree of Pulmonary Artery Stenosis and Shunt Diameters

Figure 8

3D blood flow streamlines under the 3, 4, and 5 mm shunt diameter with α of 0% and 5%. Velocity vector of LPA and RPA represents vector distribution of sections A-A and B-B (Figure 1), respectively. The velocity distribution at the cross section (section D-D in Figure 1) of the shunt is shown. The pressure distribution and velocity vector at the cross section of the shunt (section C-C in Figure 1) are also shown in the figure: (a) shunt = 3 mm α = 15%, (b) shunt = 4 mm α = 15%, (c) shunt = 5 mm α = 15%, (d) shunt = 3 mm α = 30%, (e) shunt = 4 mm α = 30%, and (f) shunt = 5 mm α = 30%.
