Mitral Stenosis Child
The most common cause of mitral stenosis is rheumatic fever . This infection may happen after strep throat or scarlet fever. It can scar the heart valves. Mitral stenosis may develop 5 to 10 years after infection.
Less common causes are:
- Structural problems that are present at birth
- Blood clots
- Infective endocarditis
- Growth that block blood flow through the mitral valve
Problems may be:
- Difficulty breathing, especially during exercise and when lying flat
- Waking up short of breath in the middle of the night
- Fast heartbeat
- Coughing up blood
- Swelling of the legs or feet
- Lightheadedness and fainting
- Chest pain (rare)
The doctor will ask about your child’s symptoms and health history. A physical exam will be done.
Images may be taken of your child's heart. This can be done with:
- Transesophageal echocardiogram
- Chest x-ray
- Cardiac catheterization
Your child's heart function may be tested. This can be done with:
- Electrocardiogram (EKG)
- Stress test
Treatment for mild stenosis may not be needed right away. The child may be monitored for changes.
Children who do need treatment may be given medicines to:
- Improve heart function
- Remove excess fluid from the body
Some children may need surgery to prevent heart damage. Choices are:
- Mitral valvulotomy to allow the mitral valve to open wider
- Balloon valvuloplasty to stretch the surrounding tissue by inflating a balloon in the mitral valve
- Mitral valve replacement to put a mechanical or tissue valve in the place of the damaged valve
