Abstract
Heart failure is a clinical entity where the heart does not function to its best so, cannot deliver adequate cardiac output to meet the metabolic demand of the body .
Heart failure is a common cause of morbidity and mortality in pediatric patients in the third world.
Compared with adult patients, where heart failure resulted from an insult to the myocardium, heart failure in children occurs due to heart lesions that cause volume overload as in large ventricular septal defect or due to lesions that causes obstruction to flow as in aortic stenosis.
Pediatric heart failure has significant consequences: it is associated with increased mortality, prolonged hospital stay, and increased economic and social burden to the family.
Acute heart failure in children in the developed communities is often due to cardiomyopathy causes or palliated congenital heart disease as opposed to developing countries where unoperated congenital heart disease and acquired heart disease are more prevalent .
