Qualitative investigation of repaired Tetralogy of
Fallot (ToF) shows that the forward and regurgitant flow
could occur in the pulmonary arteries and be recorded
simultaneously in any single cardiac phase. In this
study, we use the index of eccentricity and onset of
regurgitant flow to quantify the spatial flow profile
and the degree of flow inhomogeneity for both branch
pulmonary arteries. The results show that these spatial
indices could reflect the heterogeneous flow profile
pattern quantitatively, and thus may find useful
applications in post-surgical evaluations.
