The Fontan procedure has enabled the survival of single ventricle patients into adulthood and reduced early morbidity. However, the lack of a sub-pulmonary ventricle to pump blood flow forward into the lungs have led to serious late complications, including a failing circulation. Using computational modeling of hemodynamics, this study aims to elucidate the hydraulic operating regions to be targeted for designing a cavopulmonary pump that can support Fontan patients with failing circulations. These operating regions also provide criteria for evaluating the off-label use of commercially available blood pumps for Fontan cavopulmonary support. read more
