Rheumatic Heart Disease in Children
What is rheumatic heart disease?
Rheumatic heart disease is a condition that causes permanent damage to the heart valves.
Rheumatic heart disease follows rheumatic fever. Rheumatic fever is the body's response to a strep infection of the throat or tonsils—"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.

Your child may have signs and symptoms that affect the heart, including:
- Trouble breathing
- Chest pain

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 heart.
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 strep infection
- Steroids or nonsteroidal anti-inflammatory medicines to ease inflammation in the heart and in other parts of the body
- Water pills (diuretics) for heart failure
Your child may also need other medicines. Some children need surgery to fix or replace damaged heart valves.
