Single ventricle patients have a complex form of congenital heart disease and undergo multiple surgeries, resulting in the Fontan vasculature geometry. There is growing evidence that underlying hemodynamics in the Fontan circulation may play an important role in patient outcome. The aim of this study was to isolate flow at the Fontan connection by integrating anatomical image segmentation into the 4D flow MR analysis work flow for improved flow visualization and mixing quantification.
