What is mitral stenosis?

How do I know if I have mitral stenosis and what are the symptoms of mitral stenosis?

In adults there may be no symptoms at all. Symptoms may appear or get worse with exercise or any activity that raises the heart rate. Usual symptoms may include:

  • Chest discomfort: Patients may feel tight, crushing, pressure, squeezing, constricting, increasing with activity and decreasing with rest. And the senses may radiate to the arm, neck, jaw, or other areas.
  • Cough, possibly hemoptysis
  • Difficulty breathing during or after exercise or when lying flat
  • Fatigue
  • Frequent respiratory infections such as bronchitis
  • Palpitations
  • Swelling of feet or ankles

Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.

Who is at risk for mitral stenosis?

Clinical data has suggested that the development of mitral stenosis is related to several factors.

How to know you have mitral stenosis?

  • Echocardiogram: This kind of painless test can help the doctor closely examine the mitral valve. It uses sound waves to produce an image of the valves, ventricles and atrium. The image shows the structure of the mitral valve and its movement during the beating of the heart. Echocardiogram can tell whether mitral valve opens wide to let blood flow through or not, whether it close fully or not. Further more, the doctor can measure the speed of blood flow through patient's heart and the mitral valve area by echocardiogram.
  • Transesophageal echocardiogram (TEE): This type of echocardiogram allows an even closer look at the mitral valve than echocardiogram. During the procedure, the doctor inserts a small transducer down the esophagus that lies close to the heart. This can provide a clearer picture of the mitral valve and blood flow through it.
  • Electrocardiogram (ECG) and Holter monitoring: Electrocardiogram and Holter monitoring can tell electric activities of the heart for cardiovascular diseases. They can supply informations about heart rhythm and indirectly, heart size. Patients with mitral valve stenosis may show a heart rhythm irregularity such as atrial fibrillation and enlarged left atrium sign.
  • Cardiac MRI (magnetic resonance imaging): Cardiac MRI can create both still and moving pictures of the valves and major blood vessels. It can help doctors analyse the structure and function of the mitral stenosis and decide the treatment protocols for the patient.
  • Chest x-ray: An X-ray image of chest allows the doctor to check the size and shape of your heart to determine whether the left atrium is enlarged. And it also helps the doctor check the condition of your lungs. Patients with mitral valve stenosis may show enlarged left atrium ang congestive lungs on an X-ray.
  • Cardiac catheterization: In a catheter room, the doctor threads a thin tube through a blood vessel in your arm or groin to an artery in your heart and injects dye to see the patient's heart and the arteries on an X-ray. It can supply detailed information about the heart and the valves.

When to seek urgent medical care?

Call your health care provider if you have symptoms of mitral stenosis. Call your health care provider if you have mitral stenosis and symptoms do not improve with treatment, or if new symptoms appear. If you experience either of the following symptoms, seeking urgent medical care as soon as possible:

Treatment options

Treatment options depend on the symptoms and condition of the heart and lungs. Patients with mild symptoms or none at all may not need treatment. There are a number of different treatment options for patients with severe symptoms.

Medications: Certain drugs can be used to reduce symptoms by easing your heart's workload and regulating your heart's rhythm.

  • Antibiotics: Antibiotics may be recommend before certain dental or medical procedures to reduce the risk of bacteria entering your bloodstream and causing an infection in your heart (endocarditis).
  • Diuretics: Diuretics can be used to control pulmonary edema. There are three kinds of diuretics, loop diuretics, thiazides and potassium-sparing diuretics. The patients should take the medicines under the doctor's direction and check the blood level of electrolyes regularly.
  • Beta-blockers, digoxin and antiarrhythmic agents: These drugs can be used to control heart rate, maintain normal sinus rhythm and treat arrhythmia.
  • Anticoagulants: Anticoagulants are used to prevent blood clots from forming and traveling to other parts of the body.

Percutaneous mitral balloon valvotomy

  • Percutaneous mitral balloon valvotomy may be completed for patients with mild or moderate damaged mitral valves in a catheter room. During this procedure, the doctor inserts a tube into a vein and up into the heart. Then, a balloon on the tip of the catheter is inflated, widening the mitral valve and improving blood flow.

Valvuloplasty or mitral valve replacement:

  • The purpose of the surgery is to repair or replace the damaged mitral valves. Doctors can tell whether the patient needs surgery to treat mitral stenosis. During the procedure, the surgeons connect the patient to a heart-lung machine, which takes over the functions of the heart and lungs. Then, the surgeons can repair or replace the valve. After surgery, the patient need to take anticoagulants for a long time or the lifetime.

Prevention of mitral stenosis

Mitral stenosis itself often cannot be prevented, but complications can be prevented. Follow the health care provider's recommended treatment for conditions that may cause valve disease. Treat strep infections promptly to prevent rheumatic fever. Tell your health care provider if you have a family history of congenital heart diseases.

What to expect (Outook/Prognosis)?

The outcome varies widely. It depends on:
