Mitral Valve Disease

About Mitral Valve Disease

The mitral valve is located in the left side of your heart between two chambers: the left atrium and left ventricle.The mitral valve performs an important role in your heart as it controls the flow of blood going in one direction from the lungs to the body. If the mitral valve does not close properly, or open completely, the heart may have to work twice as hard to do its job, which can lead to life-threatening heart conditions.

Types of Mitral Valve Disease

Mitral Valve Stenosis

when the flaps or leaflets of the valve thicken, stiffen or fuse together,which  narrowing of the valve and prevents the valve from fully opening and restricting the blood flow from the left atrium to the left ventricle.

Mitral Valve Regurgitation

when the leaflets of the mitral valve don’t close tightly, allowing a portion of the blood to leak back of left atrium of your heart.

Causes and Risk factors of Mitral Disease

Causes of Mitral Valve Stenosis

  1. Rheumatic fever
  2. Older age(excessive calcium deposits )
  3. Radiation treatment to the chest
  4. Congenital heart defects
  5. Family history of mitral stenosis

Causes of Mitral Valve Regurgitation

  1. Mitral valve prolapse
  2. Damaged heart tissue cords
  3. Rheumatic fever: heart attacks
  4. High blood pressure
  5. Congenital heart defects

Symptom of Mitral Valve Disease

Symptom of Mitral Valve Stenosis

  1. Coughing
  2. Chest pain that gets worse with activity and goes away with rest
  3. Difficulty in breathing
  4. Recurrent respiratory infections such as bronchitis
  5. Heart palpitations (the feeling that the heart has skipped a beat)
  6. Swelling (edema) of the feet and ankles
  7. Irregular heart rhythms (arrhythmia)
  8. A hoarse or husky-sounding voice

Symptom of Mitral Valve Regurgitation

  1. Blood flowing turbulently through the heart (heart murmur)
  2. Fatigue
  3. fast breathing
  4. Coughing
  5. Heart palpitations — sensations of a rapid, fluttering heartbeat
  6. Swollen feet or ankles
  7. Excessive urination

Diagnosis of mitral Valve Disease

  1. Echocardiogram
  2. Electrocardiogram (ECG)
  3. Chest X-ray
  4. Cardiac computerized tomography (CT) scan
  5. Cardiac MRI
  6. Exercise tests or stress tests
  7. Cardiac catheterization

Treatment of Mitral Valve Disease

Mitral Valve Repair

In this treatment surgeon separate valve flaps (cusps) that have fused, removing excess valve tissue so that the cusps can close tightly, or patching holes in a valve.

Mitral Valve Replacement

In this treatment a surgeon will remove your damaged aortic valve and replace it with a new one from a human donor or a large animal, such as a cow or pig and mechanical valve.
