Mitral Valve Disease: Causes, Symptoms & Surgical Treatment in Lucknow

The human heart contains four valves that help maintain the correct direction of blood flow. The mitral valve is located between the left atrium and left ventricle. It opens to allow blood to flow into the left ventricle and closes when the heart pumps, preventing blood from flowing backward.

When this valve becomes narrowed or fails to close properly, it can affect the heart’s ability to circulate blood efficiently. Mitral valve disease in Lucknow requires timely medical evaluation because untreated severe valve problems may lead to complications such as heart failure, irregular heart rhythms and increased pressure in the lungs.

Understanding the causes, symptoms and available treatments can help patients recognise warning signs and seek appropriate care.

What Is Mitral Valve Disease?

Mitral valve disease refers to conditions that affect the structure or functioning of the mitral valve. The two major types are mitral stenosis and mitral regurgitation.

1. Mitral Stenosis

Mitral stenosis occurs when the mitral valve becomes narrowed and cannot open fully. This restricts blood flow from the left atrium into the left ventricle.

Common causes include:

• Rheumatic heart disease.
• Calcium deposits around the valve, particularly in older adults.
• Congenital abnormalities.
• Previous conditions affecting the heart valve.

As the narrowing becomes more severe, blood may accumulate in the left atrium and increase pressure in the blood vessels of the lungs.

2. Mitral Regurgitation

Mitral regurgitation occurs when the mitral valve does not close completely. As a result, some blood flows backward into the left atrium when the left ventricle contracts.

This can increase the workload on the heart. Over time, significant regurgitation may cause enlargement of the heart chambers and reduced heart function.

Possible causes include:

• Mitral valve prolapse.
• Damage to the valve from rheumatic heart disease.
• Infection involving the heart valve.
• Damage to the structures supporting the valve.
• Heart muscle damage following a heart attack.

Common Symptoms of Mitral Valve Disease

Some patients may have mitral valve disease without noticeable symptoms, especially during its early stages. Symptoms often depend on the severity and type of valve problem.

Common warning signs include:

1. Shortness of Breath

Breathlessness may occur during walking, climbing stairs or other physical activities. In advanced cases, some patients may experience difficulty breathing while lying down or during sleep.

2. Unusual Fatigue

When the heart cannot maintain efficient blood circulation, the body may receive less oxygen-rich blood during activity. This can lead to tiredness, weakness and reduced stamina.

3. Irregular Heartbeat

Mitral valve disease can increase the risk of abnormal heart rhythms, particularly atrial fibrillation. Patients may notice a racing, fluttering or irregular heartbeat.

4. Swelling in the Legs and Feet

Fluid accumulation may cause swelling around the ankles, feet or lower legs. This can occur when valve disease contributes to heart failure.

5. Chest Discomfort

Some patients experience chest discomfort or pressure. Chest pain should always receive medical attention because it can have several possible causes.

6. Dizziness or Reduced Exercise Tolerance

Some individuals may feel light-headed or notice that routine physical activities have become more difficult.

Sudden severe breathlessness, fainting or chest pain requires urgent medical assessment.

What Causes Mitral Valve Disease?

Mitral valve problems can develop due to several medical conditions or structural changes.

Rheumatic Heart Disease

Rheumatic fever can damage the mitral valve and cause thickening, stiffness or fusion of its leaflets. This may eventually lead to mitral stenosis or regurgitation.

Mitral Valve Prolapse

Mitral valve prolapse occurs when the valve leaflets bulge backward into the left atrium during heart contraction. In some patients, this causes mitral regurgitation.

Infective Endocarditis

Infective endocarditis is an infection affecting the inner lining of the heart, including its valves. It can damage valve tissue and interfere with normal valve function.

Heart Attack

A heart attack can damage the muscles or supporting structures responsible for proper mitral valve function. This may cause mitral regurgitation.

Age-Related Changes

Ageing may contribute to calcium deposits and structural changes around the mitral valve. These changes can affect how the valve opens and closes.

How Is Mitral Valve Disease Diagnosed?

Proper diagnosis helps doctors identify the type of valve problem, assess its severity and determine whether treatment or surgery is necessary.

The evaluation may include the following tests:

1. Physical Examination

The doctor reviews symptoms, medical history and risk factors. A stethoscope examination may reveal a heart murmur or an abnormal heart sound.

2. Echocardiography

Echocardiography is one of the most important tests for diagnosing mitral valve disease.

It uses ultrasound waves to assess:

• Mitral valve structure and movement.
• The degree of valve narrowing or leakage.
• Blood flow through the valve.
• Size of the heart chambers.
• Heart pumping function.
• Pressure changes within the heart and lungs.

A transoesophageal echocardiogram may be recommended when more detailed images are needed.

3. Electrocardiogram (ECG)

An ECG records the electrical activity of the heart. It can help identify abnormal rhythms, including atrial fibrillation.

4. Chest X-Ray

A chest X-ray may help identify enlargement of the heart or signs of fluid congestion in the lungs.

5. Cardiac CT or MRI

Doctors may recommend advanced imaging when they need additional information about heart structure, valve anatomy or associated conditions.

6. Cardiac Catheterisation

In selected cases, cardiac catheterisation helps assess pressures inside the heart and evaluate coronary arteries before treatment.

Treatment Options for Mitral Valve Disease in Lucknow

The appropriate treatment depends on the type of valve disease, its severity, symptoms, heart function and the patient’s overall health.

Some patients need regular monitoring, while others may require medication, a catheter-based procedure or surgery.

1. Regular Monitoring

Patients with mild mitral valve disease and no significant symptoms may not require immediate intervention.

Doctors may recommend regular clinical check-ups and echocardiography to monitor changes in valve function.

2. Medication

Medicines may help control symptoms and manage associated conditions.

Depending on the patient’s condition, treatment may include:

• Medicines to manage fluid retention.
• Blood pressure management.
• Medicines to control abnormal heart rhythms.
• Anticoagulants for selected patients with atrial fibrillation or other specific indications.

Medication can manage certain complications, but it generally cannot correct severe structural narrowing or leakage of the mitral valve.

3. Mitral Valve Repair Surgery

Mitral valve repair aims to restore the function of the patient’s existing valve rather than replacing it.

Depending on the valve condition, the surgeon may reshape or support the valve leaflets and repair the structures that help the valve close properly.

Possible benefits include:

• Preserving the patient’s natural valve.
• Maintaining normal valve-related heart function.
• Avoiding some long-term considerations associated with artificial valves.

Repair is not suitable for every patient. The decision depends on valve anatomy, the cause of damage and the likelihood of a durable repair.

4. Mitral Valve Replacement Surgery

When the valve is severely damaged or cannot be repaired effectively, replacement may be recommended.

The surgeon removes the affected valve and places an artificial valve.

The two main types are:

Mechanical Valve

Mechanical valves are made from durable materials and can last for many years. Patients generally need lifelong anticoagulant medication and regular blood monitoring.

Biological Valve

Biological valves are made from animal or human tissue. They may not require lifelong anticoagulation solely because of the valve, although other medical conditions may require blood-thinning medication. Their durability can be limited, and replacement may eventually become necessary.

The surgeon discusses the advantages and limitations of both options before selecting the most appropriate treatment.

5. Catheter-Based Mitral Valve Procedures

Some patients may qualify for minimally invasive procedures that treat mitral valve problems without conventional open-heart surgery.

For selected patients with significant mitral regurgitation, a procedure called transcatheter edge-to-edge repair (TEER) may be considered.

In this procedure, a catheter delivers a device to help the mitral valve leaflets close more effectively.

Suitability depends on valve anatomy, disease severity, symptoms and the patient’s surgical risk. A specialist heart team evaluates the available options.

When Is Mitral Valve Surgery Necessary?

Surgery or another valve intervention may be recommended when mitral valve disease becomes severe and causes symptoms or affects heart function.

Doctors may consider intervention in situations such as:

• Severe mitral stenosis with significant symptoms.
• Severe mitral regurgitation with symptoms.
• Changes in heart chamber size or pumping function.
• Development of complications such as pulmonary hypertension or atrial fibrillation.
• Progressive deterioration in valve function.

Not every patient needs surgery. The decision requires detailed assessment by a cardiologist and, when appropriate, a cardiothoracic surgeon.

Recovery After Mitral Valve Surgery

Recovery depends on the type of procedure, the patient’s overall health and whether other heart conditions are present.

After surgery, the medical team may focus on:

• Monitoring heart rhythm and blood pressure.
• Managing pain and preventing infection.
• Encouraging gradual movement and walking.
• Providing wound-care instructions.
• Adjusting prescribed medicines.
• Scheduling follow-up examinations.
• Recommending cardiac rehabilitation when appropriate.

Patients should follow their surgeon’s advice about exercise, lifting, driving and returning to daily activities.

Frequently Asked Questions

1. Is mitral valve disease dangerous?

Mild mitral valve disease may remain stable for years. However, severe disease can affect heart function and lead to complications such as heart failure, atrial fibrillation and pulmonary hypertension.

2. Can mitral valve disease be treated without surgery?

Some patients only need regular monitoring and medication to manage associated symptoms. Severe valve disease may require repair, replacement or a catheter-based procedure.

3. What is the difference between mitral stenosis and mitral regurgitation?

Mitral stenosis occurs when the valve becomes narrowed and restricts blood flow. Mitral regurgitation occurs when the valve does not close properly, allowing blood to flow backward.

4. Is mitral valve repair better than replacement?

Repair may be preferred when the valve can be repaired successfully and the result is expected to last. However, replacement may be necessary when the valve is severely damaged.

5. How long does recovery take after mitral valve surgery?

Recovery varies depending on the procedure and the patient’s health. Open-heart surgery generally requires a longer recovery period than selected catheter-based procedures.

6. Which test is commonly used to diagnose mitral valve disease?

Echocardiography is the primary imaging test used to assess mitral valve structure, blood flow and heart function.

Conclusion

Mitral valve disease can affect normal blood circulation and place additional strain on the heart. Early diagnosis and appropriate treatment help reduce the risk of complications and support better long-term heart health.

Treatment may include regular monitoring, medication, mitral valve repair, valve replacement or selected catheter-based procedures.
