ABSTRACT
PURPOSE OF REVIEW: Heart failure (HF) is the leading cause of morbidity and mortality in adults with congenital heart disease (ACHD), yet evidence-based pharmacological options remain limited. Sodium-glucose cotransporter 2 inhibitors (SGLT2I) have demonstrated robust benefits across the heart failure spectrum in acquired cardiovascular disease. This review is summarizing emerging data on the use of SGLT2I in ACHD, a population characterized by unique pathophysiology and unmet therapeutic needs.
RECENT FINDINGS: Recent literature, predominantly comprising case reports, retrospective cohorts, and small prospective studies, suggests that SGLT2I are generally safe and well tolerated in adult congenital heart disease heart failure (ACHD-HF). Across heterogeneous ACHD populations, including those with a systemic right ventricle (SRV) and Fontan circulation, SGLT2I use has been associated with improvements in natriuretic peptides, functional status, exercise capacity, and reductions in HF hospitalizations. Early data support favourable safety and low discontinuation rates.
SUMMARY: The use of SGLT2I in ACHD-HF is feasible, well tolerated and with potential clinical benefit. Further ACHD-specific randomized clinical trials to define efficacy, optimal patient selection, and long-term outcomes are warranted.
