- Birth defect
- Blood clots
- Infective endocarditis
- Other growths that block blood flow through the mitral valve
- Being born with mitral valve problems
- Having other health problems that affect blood flow in the heart
- Hard time breathing, especially during exercise and when lying flat
- Waking up short of breath in the middle of the night
- Sensation of rapid or irregular heartbeat

- Signs of fluid in the lungs
- Echocardiogram —can also show the motion of the heart
- Chest x-ray
- Transesophageal echocardiogram —a tube that runs from the mouth into the stomach to better examine the mitral valve
- Cardiac catheterization
- Mitral valvulotomy—A surgical cut is made in the stenotic mitral valve to allow the valve to open wider.
- Balloon valvuloplasty —A balloon is inflated in the valve to stretch out the surrounding tissue. This may provide temporary relief of symptoms but the valve may become blocked again.
- Mitral valve replacement—the valve is replaced with a mechanical or tissue valve
- Get regular medical care. This includes basic checkups and heart tests.
- Take antibiotics before any dental cleaning, dental work, or other invasive procedures if it is recommended by your doctor. Not all patients with mitral stenosis need antibiotics for these procedures.
- Eat a healthy diet that is low in salt. Work with the doctor or dietician to plan a healthy diet for your child. This may help decrease the pressure in your child’s heart and improve symptoms.
- Monitor blood pressure. Inform the doctor if your child seems to be developing high blood pressure .
- Treat strep throat infections right away to avoid rheumatic fever, which can cause scarring of the heart valve.
- Always make sure your child finishes all of the antibiotics given, even if he feels better.
