Prompt initiation of appropriate and intensive treatment in children with decompensated heart failure is crucial to avoid irreversible end-organ dysfunction. Initial management of these children includes transfer to the pediatric cardiac intensive care unit, basic hemodynamic monitoring, and establishment of intravenous access. Inotropic support should be instituted peripherally before obtaining central venous and arterial access. The team should be prepared for emergent intubation and initiation of mechanical circulatory support. Two experienced physicians should work together to obtain vascular access and manage sedation, airway control, and cardiovascular support. Acute heart failure syndrome in children may be related to cardiomyopathy, myocarditis, congenital heart disease, and acute rejection post heart transplantation. Each of these causes requires a different approach. Fulminant myocarditis may lead to severe morbidity and requires intensive support, although its outcome is considered to be good. Acute heart failure related to newly diagnosed dilated cardiomyopathy may represent end-stage heart failure; therefore, long-term mechanical circulatory support and heart transplantation may be considered to avoid other end-organ dysfunction. Hypertrophic cardiomyopathy may lead to acute decompensation due to 1) left ventricular outflow obstruction, 2) restrictive physiology leading to pulmonary hypertension, or 3) myocardial ischemia associated with coronary artery bridging. Decompensated heart failure associated with congenital heart disease usually represents end-stage heart failure and requires thorough evaluation for heart transplantation. Children with single-ventricle physiology who develop decompensated heart failure after a Fontan procedure are not candidates for mechanical circulatory support and therefore may not survive to heart transplantation. Acute heart failure due to posttransplantation acute rejection requires aggressive antirejection treatment, which places these patients at significant risk for overwhelming opportunistic infections. In our opinion, mechanical circulatory support should be initiated early in children who present with end-stage heart failure associated with hemodynamic instability to avoid end-organ damage.

Nowadays, more than 90% of all children born with congenital heart disease (CHD) reach adult life. Although initially considered to be cured, the majority of them continue to need specialised follow-up because they require re-do interventions or are at increased risk of cardiovascular complications and premature death. Arrhythmias are the most common cause of unscheduled hospital visits for grown-up CHD (GUCH) patients, accounting for one third of emergency admissions in these patients. Some GUCH patients are also at increased risk for sudden cardiac death. The principles of arrhythmia management and the prevention of sudden cardiac death in GUCH patients are similar to those used in adults with acquired heart disease, but are not evidence based. Decompensated heart failure is the other leading cause of death. Conventional medical heart-failure therapy for left ventricular dysfunction is not effective in GUCH patients at highest risk of heart failure, i.e., those with right or single ventricular failure. Careful haemodynamic assessment and structural interventions are the first step to consider in GUCH patients presenting with heart failure symptoms. Adults with moderate or complex CHD and regular follow-up in specialised GUCH centres have a survival benefit compared with patients without such follow-up. Cardiac surgery in GUCH patients should be performed by surgeons trained in treatment of CHD, i.e., surgeons also operating on paediatric patients. A structured transition programme with a defined transfer of care from the paediatric to the adult care environment is important to avoid lapses of care in today's adolescents with CHD. For GUCH patients with an intervention performed decades ago and no specific cardiac follow-up in later life, referral to a specialised GUCH centre is recommended and may save lives.
