Patient-Specific Surgery Planning for the Fontan Procedure
For children born with single ventricle heart defects, the Fontan procedure (right heart bypass via connection of caval veins to pulmonary arteries) is the palliative procedure of choice. Previous research has demonstrated strong coupling between the geometric characteristics of the surgical construct and the resulting patient-specific hemodynamics, which may relate to the numerous chronic morbidities seen in these patients. The combination of medical imaging, computer graphics and computational fluid simulations has introduced a powerful new paradigm for these procedures: providing the means to model the various options and evaluate the resulting characteristics. This paper details these methodologies, their application to planning interventions, and their contributions to generalizable knowledge of Fontan hemodynamics.
