BACKGROUND: Heart failure (HF) is the leading cause of death among adults with congenital heart disease. However, specific data on right-sided adult congenital heart disease (RACHD) remain scarce. This study assessed (1) the prevalence and risk factors of HF; (2) its prognostic impact; and (3) the impact of re-intervention in adults with right-sided residual congenital heart disease and HF (RACHD-HF). METHODS: Data from RACHD patients since 2010 were retrospectively analysed. HF was defined as symptoms requiring therapy with objective cardiac dysfunction. Cox models identified predictors of the primary composite outcome (death, ventricular assist device VAD, or heart transplant), with Kaplan-Meier curves for event-free survival. (S61354). RESULTS: < 0.001). Re-intervention was not associated with higher survival. CONCLUSIONS: HF represents a significant prognostic marker for death, VAD, or transplant in RACHD, underscoring the need for enhanced surveillance and optimised treatment. Re-intervention offers structural benefit without fully preventing adverse outcomes.
