Fig. 5.

Flow patterns in the simplified symmetric total cavopulmonary connection model (simple model). Flow is illustrated by pathlines, lines that dye or particles injected into the velocity field would follow over time. Red pathlines originate from the inferior vena cava. Blue pathlines originate from the superior vena cava. Arrows indicate inferior vena cava pathlines crossing midline to the right pulmonary artery. Flow patterns of the Newtonian and non-Newtonian fluid are not significantly different under any of the experimental conditions. IVC, inferior vena cava; SVC, superior vena cava.
