Popis: Patients who have undergone Fontan palliation have reduced exercise tolerance measured by maximal oxygen consumption (VO2 max). Declining exercise capacity is associated with increased morbidity and mortality. The impact of hemodynamics and other variables on this population’s functional status is not well understood. This study sought to identify variables that predict low VO2 max in Fontan patients living at moderate altitude (5,000–8,000 feet). We performed a retrospective cohort study of 44 adult Fontan patients living at moderate altitude who had undergone cardiopulmonary exercise testing (CPET) and cardiac catheterization. We evaluated hemodynamic parameters measured during catheterization, imaging results, and laboratory studies for correlation with VO2 max measured during CPET. Our study cohort (median age 30 years, 52% female) had exercise impairment with mean VO2 max of 21.6 mL/kg/min. Higher trans-pulmonary gradient (TPG) (p
