Mitral stenosis

Mitral valve obstruction

Treatment depends on the symptoms and condition of the heart and lungs. Persons with mild symptoms or none at all may not need treatment. Hospitalization may be required for diagnosis and for treatment of severe symptoms.

There are a number of different treatment options.

Medications include diuretics (water pills), nitrates, or beta-blockers. Digoxin may be used to treat atrial fibrillation. Anti-coagulants (blood thinners) are used to prevent blood clots from forming and traveling to other parts of the body.

Some patients may need heart surgery to repair or replace the valve. Replacement valves can be made from different materials, some of which may last for decades and others which can wear out and require replacement.

Percutaneous mitral balloon valvotomy (also called valvuloplasty) may be considered instead of surgery. During this procedure, a catheter (tube) is inserted into a vein, usually in the leg, and up into the heart. A balloon on the tip of the catheter is inflated, widening the mitral valve and improving blood flow. This procedure is less likely to work in patients with severely damaged mitral valves.

The outcome varies. The disorder may be mild, without symptoms, or may be more severe and eventually disabling. Complications may be severe or life threatening. Mitral stenosis is usually controllable with treatment and improved with valvuloplasty or surgery.

Call your health care provider if symptoms suggest mitral stenosis.

Call your health care provider if you have mitral stenosis and symptoms do not improve with treatment, or if new symptoms appear.
