Heart failure occurs when your heart muscle doesn't pump blood as well as it should.

1 Etiology and pathogenesis are different between adults and children: the first mainly relates to ischemia (60–70% of cases), the latter as a consequence of congenital heart diseases (CHDs) or cardiomyopathies in most of the cases. Heart failure isn't always apparent in children and teens.
