Acute heart failure is a common and serious complication of congenital and acquired heart disease, and it is associated with significant morbidity, mortality, and costs. When a patient is admitted to the hospital with acute heart failure, there are several important goals for the hospital admission, including maintaining adequate perfusion, establishing the underlying aetiology for the heart failure, patient and family education, and discharge from the hospital in a stable condition. The pathway to home discharge is variable and may include inotropic therapy, mechanical circulatory support, and/or heart transplantation. This review will cover the epidemiology, presentation, and management of acute heart failure in children.
