Non-uniform blood mixing (distribution of caval venous
flow to the left and right lungs) is suspected to cause
complications in patients with Fontan circulation. It
was the aim of this study to systematically analyze 3D
probabilistic flow connectivity mapping and the
influence of velocity noise on pathline visualization
for a synthetic Fontan phantom and apply these methods
in-vivo for the characterization and quantification of
blood mixing.
