Mitral Valve Disease: Causes, Symptoms & Treatment Options

An essential guide to “Mitral Valve Disease: Causes, Symptoms & Treatment Options”  from Dr. Arup Kumar Ghosh, Renowned Cardiac Surgeon in Narayana Hospital, Kolkata

Introduction

Mitral Valve Disease is one of the most common heart valve problems that can affect people of all ages. It happens when the mitral valve does not work properly, disturbing the normal flow of blood inside the heart. Many patients do not notice symptoms in the early stage, which makes awareness very important. Understanding Mitral Valve Disease causes, symptoms and treatment options can help in early diagnosis and timely care.

Today, with the growth of advanced healthcare, patients have access to high-quality Mitral Valve Surgery services that can effectively manage this condition. Treatments such as Mitral Valve Repair in Kolkata and Mitral Valve Replacement in Kolkata are now performed using modern techniques, offering better outcomes and faster recovery. Consulting an experienced Cardiac surgeon in Kolkata at the right time can make a significant difference in choosing the best treatment and improving overall heart health.

What is Mitral Valve Disease?

The mitral valve is located between the left atrium and left ventricle of the heart. Its main role is to ensure that blood flows in one direction. When this valve does not function properly, it leads to mitral valve disease.

There are mainly two types:

Mitral Valve Regurgitation

when the valve does not close properly and blood leaks backward

Mitral Valve Stenosis

when the valve becomes narrow and restricts blood flow

Both conditions affect the heart’s ability to pump blood efficiently.

Mitral Valve Disease Causes

Understanding the causes helps in early diagnosis and better treatment planning. Mitral Valve Disease can be congenital (present at birth) or acquired (develops later in life).

Rheumatic Fever

One of the most common causes is rheumatic fever, which can damage the mitral valve. It develops as a complication of untreated throat infections and can damage the valve over time.

Age-related Degeneration

With age, calcium deposits can build up on the valve, causing stiffness and narrowing.

Mitral Valve Prolapse

Some people develop the condition because of mitral valve prolapse, where the valve does not close tightly and allows blood to leak backward. Heart-related problems such as a previous heart attack or an enlarged heart can also affect the valve’s function.

Heart Conditions

• Cardiomyopathy
• Previous heart attack
• Enlarged heart

These conditions can weaken the valve structure.

Infections (Endocarditis)

Bacterial infections can damage the heart valve and lead to serious complications.

Autoimmune Diseases

Conditions like lupus can also affect the mitral valve.

Congenital Heart Defects

Some people are born with abnormal valve structure.

Symptoms of Mitral Valve Disease

The symptoms of Mitral Valve Disease often develop slowly, and in some cases, people may not notice anything in the early stage. As the condition progresses, the heart struggles to pump blood properly, leading to visible signs. As the condition progresses, common symptoms include:

One of the most common symptoms is shortness of breath, especially during physical activity or while lying down. Many people also feel tired easily, even after doing simple daily work. This happens because the body is not getting enough oxygen-rich blood.

Some patients experience a fast or irregular heartbeat, often described as a fluttering feeling in the chest. Mild chest discomfort or pressure may also occur in certain cases. Swelling in the legs, ankles, or feet is another sign, caused by fluid buildup in the body.

In more advanced stages, dizziness or light-headedness can be seen. If you notice any of these symptoms, it is important to seek medical advice early to avoid complications.

Shortness of Breath

One of the most common symptoms is shortness of breath, especially during physical activity or while lying down.

Fatigue

Many people also feel tired easily, even after doing simple daily work. This happens because the body is not getting enough oxygen-rich blood.

Irregular Heartbeat (Palpitations)

Some patients experience a fast or irregular heartbeat, often described as a fluttering feeling in the chest.

Chest Discomfort

Mild to moderate chest discomfort or pressure may also occur in certain cases.

Swelling

Swelling in the legs, ankles, or feet is another sign, caused by fluid buildup in the body.

Dizziness or Lightheadedness

In more advanced stages, dizziness or lightheadedness can be seen. If these symptoms appear, it is important to consult a Cardiac surgeon in Kolkata or a cardiologist for proper evaluation.

Complications if Left Untreated

Ignoring mitral valve disease can lead to serious health risks such as:

• Heart failure
• Atrial fibrillation (irregular heartbeat)
• Pulmonary hypertension
• Blood clots

Early treatment can prevent these complications and improve quality of life.

Diagnosis of Mitral Valve Disease

Doctors use several tests to confirm the condition:

• Echocardiogram (Echo) – main test to assess valve function
• ECG (Electrocardiogram) – checks heart rhythm
• Chest X-ray – shows heart enlargement
• Cardiac MRI or CT scan – detailed imaging

A timely diagnosis is key to choosing the right Mitral Valve Surgery services.

Treatment Options for Mitral Valve Disease

Treatment depends on the severity of the condition, symptoms, and overall health.

Lifestyle Changes

• Healthy diet
• Regular exercise (as advised by doctor)
• Avoid smoking and alcohol

Medications

Medicines cannot cure the disease but help control symptoms:

• Blood thinners
• Diuretics
• Beta-blockers

These reduce strain on the heart and improve symptoms.

Advanced Mitral Valve Surgery Services

When the condition becomes severe, surgery is often required. Modern hospitals now offer advanced and minimally invasive Mitral Valve Surgery services.

Mitral Valve Repair in Kolkata

This is usually the preferred option when possible.

Benefits:

• Preserves the natural valve
• Lower risk of complications
• Faster recovery

Techniques include:

• Valve reshaping
• Annuloplasty (tightening the valve ring)

Many experienced specialists offering Mitral Valve Repair in Kolkata use minimally invasive methods, reducing hospital stay and recovery time.

Mitral Valve Replacement in Kolkata

If the valve is too damaged, replacement becomes necessary.

There are two types of replacement valves:

• Mechanical valves – long-lasting but require lifelong medication
• Biological valves – natural tissue valves with fewer medication needs

Advanced centers providing Mitral Valve Replacement in Kolkata now use modern surgical techniques with high success rates.

Minimally Invasive & Catheter-Based Procedures

In some patients, especially high-risk cases, doctors may recommend:

• Minimally invasive heart surgery
• Transcatheter Mitral Valve Repair (TMVR)

These procedures involve smaller incisions and faster recovery.

Choosing the Right Cardiac Surgeon in Kolkata

Selecting the right specialist is very important for successful treatment.

Look for:

• Experience in valve surgeries
• Availability of advanced surgical techniques
• Hospital infrastructure and ICU support
• Patient reviews and success rates

An experienced Cardiac surgeon in Kolkata can guide you on whether repair or replacement is the best option.

Recovery After Mitral Valve Surgery

Recovery depends on the type of surgery and patient condition. Recovery after mitral valve surgery takes time, but most patients gradually return to a normal and active life. The first few days are usually spent in the hospital, where doctors closely monitor heart function and overall health. Depending on the type of procedure, such as repair or replacement, the hospital stay may last about 5 to 7 days.

Once at home, patients are advised to take proper rest and avoid heavy physical activity for a few weeks. It is normal to feel tired in the beginning, but energy levels slowly improve with time. Walking for short durations, eating a healthy diet, and taking medicines as prescribed are important parts of recovery.

Regular follow-up visits help the doctor track healing and ensure everything is on the right path. In some cases, cardiac rehabilitation programs are recommended to improve strength and confidence. With proper care and lifestyle changes, most people recover well and enjoy a better quality of life after surgery.

Tips for Faster Recovery:

• Follow doctor’s advice strictly
• Take medicines regularly
• Maintain a heart-healthy lifestyle

Prevention Tips

While not all cases can be prevented, you can reduce risk by:

• Treating throat infections early
• Maintaining good oral hygiene
• Managing blood pressure and diabetes
• Regular health check-ups
