Clinical worsening in adult congenital heart disease and heart failure: A single-centre, observational study

Data on contemporary treatment approaches and reliable markers of clinical worsening in adult patients with congenital heart disease and heart failure (ACHD-HF) are scarce. This study aimed at evaluating (1) medical therapy within a contemporary ACHD-HF cohort and (2) the incidence of various (composite) endpoints across anatomical and pathophysiological subgroups. Retrospective study including ACHD-HF patients (≥ 16 years) under active follow-up at a tertiary care center, monitored until last visit, death, ventricular assist device (VAD) implantation, or heart transplant (HTX). Medical therapy was documented at time of inclusion and final follow-up. Clinical endpoints were evaluated, after excluding patients with early events (
