Hypoplastic Left Heart Syndrome Is Not a Predictor of Worse Intermediate Mortality Post Fontan

Martin and colleagues analyzed in-hospital complications, transplant-free survival, and long-term reintervention for patients receiving a Fontan operation over 20 years, with a specific focus on differences between patients with and without hypoplastic left heart syndrome (HLHS). The authors found that patients with HLHS were more likely to require intervention for atrioventricular valve regurgitation but not for Fontan failure. Ten-year overall and transplant-free survival were also the same for patients with and without HLHS.
