Mitral Valve Disease

What is mitral valve disease?

The mitral valve controls blood flow from the lungs into the heart by separating the upper left chamber called the left atrium and the lower chamber called the left ventricle. It can become narrowed (stenosis) or start to leak (regurgitation) causing a backwards flow from the left ventricle, back into the left atrium. This reduces the amount of oxygen rich blood being pumped around the body.

Mitral Stenosis is typically the result of scarring from rheumatic fever in childhood.

Mitral regurgitation may occur as a result of age related degeneration, infection, enlargement of the heart or after a heart attack.

Mitral regurgitation may occur as a result of inflammation of the heart’s lining, endocarditis or after a heart attack. It may also develop due to wear and tear.


What are the symptoms of mitral valve disease?

Problems with the mitral valve can cause shortness of breath, palpitations and dizziness.



What assessment do I need if I have mitral valve disease?

Firstly, your doctor will have taken a full history from you. If Mitral Valve Disease is suspected, an ECG and echocardiogram will probably be requested to confirm. Ambulatory Holter Monitoring and Transoesophageal Echocardiography may also be indicated depending on your symptoms and the information obtained from the other investigations.


What are the treatments for mitral valve disease?

Treatment depends on the severity of the problem and may include medication to control the underlying cause or mitral valve repair or replacement.

  • Atrial Fibrillation (AF) Catheter Ablation

    This is an invasive procedure to block the electrical signals causing atrial fibrillation and to restore sinus rhythm. [READ MORE]

  • Atrial Flutter Ablation

    This procedure blocks the electrical signals that cause a fluttering heartbeat and restores sinus rhythm. [READ MORE]

  • CTCA Scan & Calcium Score

    This scan is used to ascertain the risk of a heart attack or stroke within the next 5-10 years. [READ MORE]

  • Echocardiogram (TTE)

    An ‘echo’ is an ultrasound scan of the heart to assess structure and function. [READ MORE]

  • MRI Scan / CMR Scan

    These scans enable cardiologists to view detailed images of the heart’s anatomy. [READ MORE]

  • Transoesophageal Echocardiogram (TOE)

    Sometimes an ‘echo’ scan of the heart requires an ultrasound probe to be passed down the food pipe to provide a clearer image. [READ MORE]
