Patients who underwent a Fontan procedure for single ventricle physiology were evaluated with serial cardiac MR over time to identify changes in vessel characteristics and their relationship to flow. Although vessel diameter increased over time, normalized diameters decreased. This was not associated with changes in flow, but hemodynamic efficiency declined over time.
