043 Feasibility, Efficacy and Safety of PDA Stenting With IBS ® in Duct-Dependent Cyanotic CHD

Abstract

failures per 100 patient-year follow-up; versus 0.99 for controls). The 5, 10, 15 and 20-year freedom from failure were 95%, 91%, 88% and 83% respectively in the early Fontan group, and 97%, 92%, 86% and 80% respectively in the control group (log rank p=0.8; Fig. 1). In the adjusted analyses, including for surgical era, early age at Fontan completion was not a risk factor for long-term failure (HR 1.29, 95% CI 0.84-1.97, p=0.24), new-onset arrhythmia (HR 1.01, 95% CI 0.67-1.52, p=0.95) or re-intervention (HR 1.18, 95% CI 0.88-1.58, p=0.28). Subgroup analysis (lateral tunnel and extracardiac conduit) produced similar results. Conclusion: Earlier age at operation (,3 years) is not a risk factor for short-or long-term adverse outcomes after the Fontan procedure.
