MITRAL VALVE DISEASE

Mitral valve disease disrupts the heart’s normal blood flow and can lead to symptoms such as breathlessness, fatigue, palpitations, or chest discomfort. It occurs when the mitral valve does not open or close properly, affecting how blood flows through the heart. Sometimes, it may cause blood to leak backwards or restrict forward flow. Early diagnosis is essential to prevent complications and protect long-term heart health.

Mitral valve disease

WHAT IS THE MITRAL VALVE?

The mitral valve is one of the four heart valves, located between the left atrium and the left ventricle. Its role is to ensure smooth, one-way blood flow from the left atrium into the left ventricle while preventing any backward leakage. The valve comprises two thin flaps of tissue, known as leaflets, which open to pass blood through them and close to stop any backflow, thus helping maintain proper blood circulation.

FORMS OF MITRAL VALVE DISEASE

  • Mitral Valve Regurgitation

    In Mitral regurgitation, the flaps of the mitral valve can not close properly, which causes blood to leak backwards, i.e., from the left ventricle to the left atrium. This backward leakage of blood increases pressure in the lungs and reduces the heart’s pumping efficiency. 
    Over time, untreated regurgitation may lead to symptoms, such as breathlessness, fatigue, or, in severe cases, heart failure. Early diagnosis allows for careful monitoring and timely treatment.
  • Mitral Valve Stenosis

    Mitral stenosis occurs when the heart’s mitral valve becomes narrowed, restricting normal blood flow into the left ventricle. If left untreated, a stenotic mitral valve can cause serious heart complications.

SYMPTOMS OF MITRAL VALVE DISEASE

Symptoms of Mitral Valve Regurgitation

Mitral regurgitation often develops silently without any obvious symptoms for years. Commonly, they may show symptoms such as:

  • Irregular heartbeat (arrhythmia)
  • Palpitations
  • Breathlessness, especially on exertion
  • Persistent fatigue
  • Oedema (Swelling in the feet or ankles)
  • Reduced Exercise tolerance

Symptoms of Mitral Valve Stenosis

Mitral stenosis often develops gradually but can significantly impact daily life. Common symptoms include:

  • Shortness of Breath
  • Irregular heart rhythm (arrhythmia)
  • Extreme tiredness
  • Oedema
  • Chest pain
  • Dizziness or fainting
  • Heart murmurs

WHAT CAUSES MITRAL VALVE DISEASE?

Common Causes of Mitral Regurgitation

  • Rheumatic Fever
  • Congenital Heart Defects
  • Thickening of the heart muscle (cardiomyopathy)
  • Mitral annular calcification
  • Mitral annular disjunction
  • Heart Attack

Common Causes of Mitral Stenosis

  • Rheumatic heart disease
  • Certain radiation therapies for cancer
  • Congenital Defects
  • Autoimmune diseases

DIAGNOSIS OF MITRAL VALVE PROBLEMS

Accurate and timely diagnosis is essential to determine the type and severity of valvular heart disease and guide the most appropriate treatment. A detailed consultation with Dr Francesco Lo Monaco in Harley Street, London, provides a thorough evaluation of your symptoms, medical history, and overall cardiovascular risk. 

Your assessment begins with a comprehensive clinical review, including discussion of symptoms such as breathlessness, palpitations, or fatigue, along with a physical examination and relevant family history. It gives a clear understanding of whether a mitral valve condition may be present and what level of investigation is required. 

As a preventive cardiologist, Dr Francesco Lo Monaco focuses on early detection and long-term heart health, combining lifestyle guidance with targeted diagnostics to ensure the most effective management plan. Where needed, further investigations may include:

Following your assessment, you will receive a clear explanation of your diagnosis along with a personalised plan, whether that involves monitoring, lifestyle changes, or further specialist care.

LIFESTYLE CHANGES TO TREAT MHD

Making the right lifestyle adjustments can help manage symptoms, support heart function, and improve long-term cardiovascular health. Dr Francesco Lo Monaco may recommend the following lifestyle changes to help manage Mitral Valve Disease:

  • Quit Smoking
  • Limit Caffeine and Alcohol Consumption
  • Follow a Heart-Healthy Diet
  • Manage Stress
  • Maintain a Healthy Weight
  • Engage in Regular, Moderate Physical Activity

WHEN SHOULD YOU SEEK SPECIALIST CARE?

You should consider consulting your cardiologist if you experience:

  • Breathlessness during normal routine activities
  • Frequent or worsening palpitations
  • Persistent fatigue even with rest
  • Swelling in the ankles or feet
  • Chest discomfort or pressure
