Bacterial Endocarditis in Children
Bacterial endocarditis is an infection of the inner lining of the heart (endocardium),
or the heart valves. It doesn't occur in children very often, but when it does, it
cause serious heart damage.
Bacterial endocarditis occurs when bacteria in the blood enter the heart and cause
infection of the heart.
Bacteria can enter the body in many ways. Having heart problems, especially with the
valves, raises the chance that bacteria will affect the heart. Some of the most common
ways bacteria get into the blood include:
- Dental work, such as professional teeth cleaning
- Surgery to remove the tonsils or adenoids
- Medical procedures, such as an exam of the airways with a bronchoscope
- Surgery, such as some respiratory, gastrointestinal, or urinary tract surgeries
child is at higher risk for bacterial endocarditis if they have:
- Artificial (prosthetic) heart valves
endocarditis in the past
- Congenital (at birth) heart disease
- Had a
heart transplant (immunocompromised), but the heart valves aren't working
- Indwelling central venous catheter
- Rheumatic heart disease
- A weak immune system
Talk with your child's healthcare provider about your child's risk factors.
Symptoms can occur a bit differently in each child. They can include:
- Flu-like symptoms, such as fever, chills, tiredness, aching muscles and joints,
night sweats, and headaches
- Shortness of breath
changes such as:
- Pale skin
- Bumps under the skin on the fingers and toes
- Spots on the palms of the hands and soles of the feet
- Small broken blood vessels with tiny spots under the
nails, on the whites of the eyes, in the mouth, or on the chest
and vomiting, decreased appetite, weight loss
- Discomfort in the belly
in the urine
of the feet, legs, or abdomen
healthcare provider will ask about your child’s symptoms and health history. They
give your child a physical exam and listen to your child's heart. Other tests may
Echocardiogram (echo). This test looks at the structure of your child's
heart and how well it's working. It uses sound waves to make a moving picture of the
heart and heart valves. Your healthcare provider may be able to see a heart valve
This test looks for infection in your child's blood.
Complete blood count (CBC).
This test looks at all types of cells in your child's blood. These are red cells,
white cells, and platelets.
Treatment will depend on your child’s symptoms, age, and general health. It will also
depend on how severe the condition is.
A child heart specialist (pediatric cardiologist) and an infectious disease specialist
will take care of your child. Treatment includes:
Antibiotics. Antibiotics are usually given through the vein (IV) for several
weeks. Your child will likely be in the hospital to get the medicine. Sometimes these
antibiotics can be given at home with the help of a home-based healthcare team.
Some children may need heart valve surgery if there is severe heart valve
damage due to the infection. This is done to fix or replace a damaged heart valve.
a child may need surgery to help clean out the endocarditis. This may be done if the
antibiotics don’t work well enough on the infection.
Complications of bacterial endocarditis include:
- Heart failure
clots or clumps of bacteria that travel to other parts of the body (emboli). This
might travel to the arteries in the heart, brain, spleen, bowel, arms, or legs.
- Infection in other parts of the heart
- Weakened blood vessel (aneurysm), such as in the brain
injury or disease
Bacterial endocarditis can't be entirely prevented. But some things can help. They
your child take very good care of their teeth and gums
your child to the dentist for regular cleaning and checkups
- Practice good hygiene
- Have your child take the full prescription of antibiotics when
these are used to treat infections such as strep throat
Some children with heart problems need to take antibiotics before some dental and
medical procedures. Talk with your child's healthcare provider to find if your child
Your child will need ongoing care, including:
- Repeat echocardiograms and blood tests after the infection
- Regular health checkups
- Regular dental checkups
daily oral hygiene (brushing and flossing)

- Symptoms are similar to the flu. Other symptoms include a cough, skin changes, and
swelling in the arms, legs, or abdomen.
- Bacterial endocarditis is treated with antibiotics or surgery.

- Good dental care and body hygiene is an important part of preventing bacterial endocarditis.
