What is Mitral Stenosis?

Mitral Stenosis occurs when the opening of the mitral valve becomes narrowed, making it harder for blood to move from the left atrium into the left ventricle. Rheumatic heart disease is the most common cause worldwide, although mitral stenosis can also result from valve calcification, congenital abnormalities, or other less common conditions. Severe disease can lead to pulmonary hypertension, atrial fibrillation, heart failure, and other complications.

What is the Importance of Timely Treatment?

Timely treatment can help relieve breathlessness and other symptoms, reduce pressure on the heart and lungs, manage complications such as atrial fibrillation, and prevent worsening heart failure. Regular assessment also helps determine whether monitoring, medicines, percutaneous mitral balloon commissurotomy, or surgery may be appropriate based on valve anatomy and disease severity.

What are the Common Symptoms of Mitral Stenosis?

  • Shortness of Breath: Breathlessness may occur during physical activity and can become more noticeable as the valve narrowing progresses.
  • Fatigue: Reduced blood flow into the left ventricle may contribute to tiredness and reduced physical endurance.
  • Palpitations: An irregular or rapid heartbeat may occur, particularly when atrial fibrillation develops.
  • Reduced Exercise Tolerance: Routine activities may become increasingly difficult because of breathlessness or fatigue.
  • Swelling: Fluid retention may cause swelling of the ankles, feet, or lower legs, particularly in more advanced disease.
  • Dizziness or Chest Discomfort: Some patients may experience lightheadedness or chest discomfort, especially during exertion.

Causes and Risk Factors of Mitral Stenosis

Causes

  • Rheumatic Heart Disease: Previous rheumatic fever can cause progressive scarring and narrowing of the mitral valve and remains the most common cause worldwide.
  • Mitral Valve Calcification: Calcium deposits can progressively restrict valve movement, particularly in older adults.
  • Congenital Mitral Stenosis: Some people are born with mitral valve abnormalities that cause narrowing.
  • Autoimmune or Inflammatory Conditions: Conditions such as lupus can rarely contribute to mitral valve disease.
  • Other Structural Valve Changes: Less common abnormalities may also interfere with normal mitral valve opening.

Risk Factors

  • Previous rheumatic fever or rheumatic heart disease
  • Increasing age
  • History of valvular heart disease
  • Congenital heart abnormalities
  • Conditions associated with valve calcification
  • Certain autoimmune or inflammatory diseases
  • Previous heart-valve procedures

Latest Research and Technologies in the Treatment of Mitral Stenosis in India

  • Current advances in mitral stenosis care include multimodality cardiac imaging, three-dimensional echocardiography, transesophageal echocardiography, cardiac CT, and advanced catheter-based assessment to define valve anatomy and treatment suitability.

Treatment options for Mitral Stenosis

Percutaneous Mitral Balloon Commissurotomy (PMBC): Also known as Percutaneous Mitral Valvuloplasty (PMV), this is a catheter-based, first-line mechanical treatment to split open fused leaflets in patients with favourable rheumatic anatomy (measured via a low Wilkins score).

Mitral Valve Replacement (MVR) : The standard open-surgical option using either a mechanical or bioprosthetic valve, reserved for patients with severe calcification, distorted subvalvular apparatus, or concurrent severe mitral regurgitation.


Cost Start From 4000Explore Options

Transcatheter Mitral Valve Replacement (TMVR): This specialised procedure (such as valve-in-mitral-annular-calcification, or ViMAC) is an emerging option for elderly, high-risk patients with degenerative disease who cannot undergo open surgery.

  • Clinical assessment:
    • Medical History: Assessment of breathlessness, fatigue, exercise tolerance, palpitations, previous rheumatic fever, heart disease, and medications.
    • Physical Examination: Evaluation of heart sounds, heart rhythm, blood pressure, oxygen saturation, signs of fluid retention, and other cardiovascular findings.
    • Electrocardiogram (ECG): May identify atrial fibrillation, heart-rate abnormalities, or other cardiac changes.
    • Blood Tests: Blood tests may assess kidney function, electrolytes, blood counts, and other factors relevant to treatment.
    • Exercise Testing: Exercise or stress testing may be considered when symptoms and resting valve measurements do not clearly correspond.
  • Imaging Tests:
    • Transthoracic Echocardiography (TTE): The standard initial imaging test used to assess valve structure, valve area, blood-flow gradients, heart chambers, and pulmonary pressures.
    • Transesophageal Echocardiography (TEE): Provides detailed images of the mitral valve and left atrium and may be used before percutaneous commissurotomy to assess for blood clots and valve anatomy.
    • Three-Dimensional Echocardiography: Provides detailed assessment of valve morphology and can support procedural planning in selected patients.
    • Cardiac CT: May provide additional anatomical information, particularly when valve or mitral annular calcification needs further assessment.
    • Cardiac MRI: Provides detailed information about heart structure and function in selected patients.
    • Chest X-ray: May show enlarged cardiac chambers or changes associated with pulmonary congestion.
    • Cardiac Catheterisation: Can measure pressures within the heart and pulmonary circulation when non-invasive testing does not provide sufficient information or before selected interventions.

MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive rehabilitation services designed to support Mitral Stenosis patients in India. These services include:

  • Cardiac Rehabilitation: Structured rehabilitation may help improve exercise capacity and support recovery after valve procedures.
  • Gradual Physical Activity: Increase activity according to symptoms, valve severity, heart function, and medical advice.
  • Breathing and Functional Training: Selected patients may benefit from supervised exercises to improve functional capacity.
  • Long-Term Cardiac Follow-Up: Regular cardiology and valve-clinic assessments help monitor valve function, heart rhythm, symptoms, and treatment response.
  • Medicines for Mitral Stenosis may include diuretics, heart-rate controlling medicines, medicines for atrial fibrillation, and anticoagulants when indicated. These treatments can reduce symptoms and manage complications but do not reverse severe mechanical narrowing of the mitral valve. In rheumatic mitral stenosis with atrial fibrillation, anticoagulation decisions require particular consideration because thromboembolic risk is increased.

Frequently Asked Questions

Recovery depends on the severity of the condition and the treatment performed. Recovery after percutaneous balloon commissurotomy is generally shorter than recovery after open-heart surgery, while patients with untreated or chronic disease may require long-term monitoring and management.

Many people with mild or stable mitral stenosis can remain physically active. However, adjust activity based on the severity of valve narrowing, symptoms, heart rhythm, and pulmonary pressures. Patients with significant symptoms should receive medical guidance before increasing exercise.

Many advanced Indian cardiac centres offer echocardiography, transesophageal and 3D echocardiography, cardiac CT and MRI, cardiac catheterisation, percutaneous mitral balloon commissurotomy, valve surgery, intensive cardiac care, and cardiac rehabilitation.

Many major Indian hospitals have international patient departments that help overseas patients with medical records, appointments, treatment coordination, accommodation, interpretation (where available), and follow-up arrangements.

Search for a centre with experienced cardiologists, interventional cardiologists, cardiac surgeons, advanced echocardiography, catheterisation facilities, and access to a multidisciplinary heart-valve team. For complex disease, experience with the specific mitral procedure being considered is also important.

There is no single success rate because outcomes depend on the cause and severity of stenosis, valve anatomy, heart function, pulmonary pressures, heart rhythm, age, associated conditions, and the treatment performed. Discuss individual outcomes with the treating heart-valve team.

Many Indian cardiac centres have cardiologists, interventional cardiologists, and cardiac surgeons experienced in evaluating and treating mitral valve disease through medical management, catheter-based procedures, and surgery.

Risks depend on the treatment. Medicines can cause side effects, and anticoagulants can increase bleeding risk. Balloon commissurotomy may involve bleeding, valve leakage, arrhythmias, blood-vessel complications, or other procedural risks. Surgery may involve bleeding, infection, arrhythmias, stroke, kidney complications, or anaesthesia-related complications.

Mitral stenosis is a heart-valve condition, not an injury. If you develop severe or rapidly worsening breathlessness, fainting, chest pain, severe palpitations, or symptoms at rest, seek prompt medical attention.

Mitral stenosis does not directly cause physical or skeletal deformities. However, advanced disease can cause pulmonary hypertension, heart failure, reduced exercise capacity, or other complications that may affect long-term physical functioning.

Yes. Breathlessness, fatigue, palpitations, reduced exercise tolerance, and limitations in daily activities can affect quality of life. Appropriate medical management, valve intervention when indicated, rehabilitation, and regular follow-up can help manage symptoms and functional limitations.

Yes. Untreated significant mitral stenosis can progressively increase pressure in the left atrium and lungs and may contribute to atrial fibrillation, pulmonary hypertension, heart failure, blood clots, and other cardiovascular complications.

Not all causes can be prevented. Preventing and appropriately treating streptococcal infections and rheumatic fever can help reduce the risk of rheumatic heart disease. Regular medical follow-up is important for people with known valve disease so providers can identify progression and complications early.

Yes. Rheumatic mitral stenosis is more common in regions and populations where rheumatic heart disease remains prevalent. Mitral stenosis related to valve calcification is more commonly seen with increasing age. People with a history of rheumatic fever, congenital valve abnormalities, or certain inflammatory conditions may also have an increased risk.
