Pediatric Myocarditis

Look up a term in The Heart Center glossary.Myocarditis is a condition where the muscular walls of the heart become inflamed. Myocarditis typically results in poor heart function.

There are many causes of myocarditis, including:

  • Infection
  • Medications
  • Chemicals
  • Radiation
  • Certain diseases that cause inflammation in many different organs of the body 

In most children, myocarditis is triggered by an infection, usually viral, involving the heart.

There are no known risk factors for developing myocarditis. Age, sex, and genetic make-up may all play a role in how severe the disease becomes once you have it.

Treatment for myocarditis is based on how badly the heart is affected. Many children have a complete recovery, but some may develop serious heart failure and require chronic care from a cardiologist.
