Heart failure in adults with congenital heart disease.

Heart failure (HF) represents the leading cause of morbidity and mortality in adult patients with congenital heart disease. The nature of underlying congenital heart disease has bearing on timing and severity of HF and impacts on short- and long-term outcomes. HF can be subclinical, underscoring the need for close follow-up at tertiary centres with timely management of target hemodynamic lesions. Drug therapies have an effect in systemic left ventricle failure and are employed in acute HF for symptomatic relief. Data on elective drug therapy for the failing systemic right ventricle and/or Fontan circulation is currently lacking. Drugs such as angiotensin receptor blockers with neprilysin inhibitors or sodium-glucose co-transporter-2 inhibitors may show benefit. Cardiac resynchronization therapy, in appropriately selected patients, is considered a treatment option. Mechanical circulatory support and transplantation remain the last resource in highly selected patients. As the congenital heart disease population continues to grow and age, both outpatient and inpatient service for HF will continue to play a major role in the care of adult patients with congenital heart disease.
