Rheumatic Heart Disease in Children
What is rheumatic heart disease?
Rheumatic heart disease is a condition that causes permanent damage to the heart valves.
It follows rheumatic fever. Rheumatic fever is the body's response to a strep infection
of the throat or tonsils or "strep throat." Rheumatic fever may also follow scarlet
fever. This is a strep infection of the throat along with a red, rough-feeling skin
rash. Rheumatic fever may affect the joints, skin, tissue under the skin, brain, and
heart. If it affects the heart, it is called rheumatic heart disease.
What causes rheumatic heart disease?
Rheumatic heart disease is caused by rheumatic fever. Rheumatic fever is a complication
of an untreated or under-treated strep infection.
Who is at risk for rheumatic heart disease?
Rheumatic heart disease is uncommon in the U.S., because rheumatic fever is also not
common. Rheumatic fever occurs more often in children between ages 5 and 15. This
is especially true if they have had frequent cases of strep throat. Poor access to
medical care is a risk factor for rheumatic heart disease as strep infections are
more likely to be missed and go untreated.
What are the symptoms of rheumatic heart disease?
Your child may have signs and symptoms that affect the heart, including:
- Trouble breathing
- Chest pain
- Swelling (edema) of the feet and ankles
- Heart murmur
Your child may also have other signs and symptoms of rheumatic fever. These include:
- Joint pain and swelling
- Small, hard, round bumps under the skin (nodules)
- Irregular or jerky movements
- Belly (abdominal) pain
- Bloody nose
The symptoms of rheumatic heart disease can be like other health conditions. Make
sure your child sees his or her healthcare provider for a diagnosis.
How is rheumatic heart disease diagnosed?
The healthcare provider will ask about your child’s symptoms and health history, including
having rheumatic fever or strep infections. He or she will give your child a physical
exam. Your child may also have tests, such as:
- Throat culture
- Electrocardiography. A test to measure the electrical activity of the heart.
- Echocardiography. An imaging test that uses sound waves (ultrasound) to make detailed pictures of the
- Blood tests
How is rheumatic heart disease treated?
Treatment will depend on your child’s symptoms, age, and general health. It will also
depend on how severe the condition is. Your child's healthcare provider will likely
refer you to a pediatric cardiologist. This is a doctor with special training to treat
heart problems in children. Your child may also see other specialists, depending on
his or her symptoms.
Children with rheumatic heart disease will need to rest until their symptoms get better.
Your child’s healthcare provider may prescribe one or more of these medicines:
- Antibiotics to treat the acute strep infection
- Long-term antibiotics to prevent recurrent strep infection
- Steroids or nonsteroidal anti-inflammatory medicines to ease inflammation in the heart
and in other parts of the body
- Water pills (diuretics) if heart failure develops
- Anti-inflammatory medicine for the management of fever and arthritis symptoms
Your child may also need other medicines. Some children need surgery to fix or replace
damaged heart valves.
What are the complications of rheumatic heart disease?
Complications of rheumatic heart disease include:
- Permanent heart damage
- Heart failure
- Infection in the heart (endocarditis)
Can rheumatic heart disease be prevented?
You can help prevent rheumatic fever and rheumatic heart disease by knowing what strep
throat looks like and getting treatment for it. Your child’s healthcare provider
can do a throat culture or rapid antigen detection test (RADT) to see if your child
has strep throat.
Children with damaged heart valves from rheumatic heart disease need to keep their
teeth and gums clean. They should also have regular dental exams with preventive antibiotics.
These steps can help prevent infections of the damaged heart valves.
How is rheumatic heart disease managed?
Your child will need to have regular exams to check on his or her heart. He or she
may also have repeat diagnostic tests of the heart.
If your child has had rheumatic fever, the healthcare provider may prescribe periodic
antibiotics to take for several years or up to a certain age. The antibiotics keep
rheumatic fever from coming back. They also lower the risk for heart damage. It is
important that your child continue to take antibiotics as prescribed.
When should I call my child's healthcare provider?
Call your child's healthcare provider if your child has any of the following:
- Trouble breathing
- Chest pain
- Swelling (edema) of the feet or ankles
- Another sore throat
