Heart Valve Disease

Your heart valves keep blood moving in the right direction with each heartbeat. If a valve becomes narrow or starts leaking, it can change how blood flows and how hard your heart has to work.

Many valve problems can be monitored without a procedure. Others need treatment to relieve symptoms or protect the heart, sometimes before you notice any difficulty. The right approach depends on the valve involved and what the examination and scans show.

Your heart has four valves: the mitral, aortic, tricuspid and pulmonary valves. They work like one-way doors. They open to let blood move forward and close to prevent it flowing backwards as the heart fills and pumps.

A healthy valve needs to open freely and close properly. When either action is affected, blood flow through the heart can change.

What happens when a valve narrows or leaks?

There are two main types of valve problem:

One valve can have both narrowing and leakage. More than one valve can also be affected.

Echo reports often use abbreviations such as MR for mitral regurgitation, AR for aortic regurgitation or TR for tricuspid regurgitation. The abbreviation identifies the valve problem; the rest of the assessment tells us how important it is.

No. Valve disease affects the structures controlling blood flow through the heart. A heart attack involves injury to the heart muscle because its blood supply becomes inadequate, usually when a coronary artery becomes blocked.

Having valve disease does not mean you have had a heart attack or will inevitably have one. However, valve disease and coronary artery disease can occur together. A heart attack can also affect the structures supporting a valve and cause leakage.

Chest pain should never be dismissed as “just the valve.” New or persistent chest pain needs prompt assessment.

Age-related changes are a common cause in older adults. Valves can thicken, become less flexible or accumulate calcium. However, the cause varies with the valve involved and the person's age and medical history.

• Calcium and degenerative changes: These can affect the aortic valve or the ring around the mitral valve. Calcium may be present without causing a major flow problem, or it may contribute to narrowing or leakage.
• Rheumatic heart disease: Previous rheumatic fever can scar valves, particularly the mitral valve. Some people do not remember an earlier illness. This remains an important cause to consider in Indian patients.
• Differences present from birth: For example, a bicuspid aortic valve has two leaflets rather than the usual three and may develop narrowing or leakage.
• Changes in the valve or its supporting structures: Mitral valve prolapse or damaged supporting cords can prevent a valve closing properly.
• Changes in the heart muscle or chambers: Enlargement, weakness or altered chamber shape can pull an otherwise relatively normal valve apart, causing secondary leakage.
• Infection: Infective endocarditis can damage a valve and sometimes requires urgent treatment.

Not necessarily. Aortic sclerosis means thickening or calcification without significant obstruction to blood flow. It is different from aortic stenosis. It warrants interpretation in context, rather than an automatic recommendation for replacement.

Mitral annular calcification means calcium around the ring supporting the mitral valve. Its significance depends on whether it affects valve opening or closure and on the rest of the heart assessment. The word “calcification” alone does not establish a need for treatment.

Symptoms may develop gradually. You may notice that a familiar walk feels harder, that you pause on stairs more often, or that ordinary household activities leave you unusually tired.

Other symptoms can include:

• Breathlessness during activity, when lying flat or during the night.
• Chest discomfort, dizziness or fainting, particularly with exertion.
• A racing, irregular or fluttering heartbeat.
• Swelling of the ankles, legs or abdomen.

These symptoms can have other causes too. Swollen feet alone do not prove a valve problem, and every episode of breathlessness is not caused by valve disease.

Can a valve problem be found when I have no symptoms?

Yes. It may be discovered after a doctor hears a murmur, or during an echo performed for another reason. A murmur is a sound produced by blood flow; some murmurs are harmless, while others need investigation.

An incidental finding may be minor, but feeling well does not by itself tell us how severe the condition is. Some people gradually reduce their activity without recognising that their exercise capacity has changed.

What do mild, moderate and severe mean?

These terms describe the degree of narrowing or leakage. They are not percentages of heart damage and do not, on their own, decide treatment.

“Report ma valve leak lakhyu chhe. Shu operation karavvu padshe?” If your report mentions leakage, an operation is not an automatic next step. First, we need to understand the valve, the severity and its effect on your heart.

Assessment starts with your symptoms, medical history and examination. An echocardiogram with Doppler is the main imaging test. It uses ultrasound to show the valves and assess blood flow.

The assessment looks beyond a single label. It considers valve structure, opening and leakage, heart chamber size and function, and pressure changes caused by the valve problem. Previous scans help establish whether anything is changing.

Can an echo report have limitations?

Yes. Image quality and measurement technique matter. Blood pressure, heart rhythm and the amount of blood flowing through the valve can affect measurements. A low pressure difference across a valve does not always exclude important narrowing.

When findings do not fit together, further assessment may include an echo through the food pipe, called transoesophageal echo or TEE, CT, cardiac MRI or selected supervised exercise testing. These tests answer particular questions; everyone does not need all of them. Exercise testing is not appropriate for every valve condition, particularly symptomatic severe aortic stenosis.

Monitoring means having a clear plan: when to return, whether another echo is needed and which changes should prompt earlier contact. It is intended to identify progression before important damage develops.

There is no single repeat-echo schedule for every valve problem. Follow-up depends on the valve, severity, symptoms, chamber changes and speed of progression. Mixed valve disease, pregnancy or associated heart failure can change that plan.

Bring previous reports and echo images when available. Tell your doctor about a shorter walking distance, new breathlessness, fainting, swelling or palpitations rather than waiting for the next scheduled scan.

“Dava thi saaru thai jashe ke valve badalvo padshe?”

The answer depends on what is causing the problem.

Medicines can relieve fluid build-up, manage blood pressure or heart rhythm, and reduce clot risk when there is a reason to use anticoagulation. They cannot mechanically reopen a scarred or heavily calcified valve or repair a torn valve leaflet.

There is an important exception to the idea that medicines cannot improve leakage: secondary leakage caused by changes in the heart muscle or chambers may lessen when the underlying condition is treated. Appropriate heart failure treatment, rhythm management and, in selected patients, device therapy may therefore come before a valve procedure.

Not everyone with valve disease needs blood thinners. Mechanical replacement valves and significant rheumatic mitral stenosis require particular anticoagulation decisions. Do not substitute one blood thinner for another without medical advice.

For people with rheumatic disease, prescribed antibiotics may help prevent recurrent rheumatic fever and further damage. They do not reverse established valve scarring.

A procedure is considered when the expected benefit outweighs its risks. Symptoms matter, but so do changes in heart size or function, lung pressures, disease progression and the need for another heart operation.

The timing differs between conditions:

• Aortic stenosis: Severe narrowing with symptoms usually requires valve intervention if it is expected to help. Selected people with severe disease may benefit before symptoms become obvious.
• Aortic leakage or primary mitral leakage: Treatment may be appropriate before symptoms if the heart is enlarging or showing early functional changes. An apparently reassuring pumping measurement does not settle the decision by itself.
• Secondary mitral leakage: Treat the underlying heart condition first, then assess whether significant symptoms and leakage persist.
• Tricuspid disease: Assessment includes the right side of the heart and effects on other organs. Waiting until advanced damage can limit treatment options.

“Mujhe koi takleef nahi hai, phir treatment kyun?”

Sometimes the aim is to protect the heart before damage becomes difficult to reverse. In other situations, close follow-up is appropriate. Dr. Kulin will explain which findings support the recommendation in your case.

Not every valve problem needs an operation, and not every valve procedure requires the chest to be opened.

Some conditions need monitoring. When intervention is appropriate, treatment may involve surgery or a thin tube called a catheter, usually introduced through a blood vessel in the groin. The method depends on the valve and the problem being treated.

“Shu chhati kholine operation karavvu padshe?”

This is an important question to ask. A catheter approach may be suitable, but surgery may offer a more complete or durable treatment for another person. Smaller-incision heart surgery is also possible in selected cases; it remains surgery and differs from a catheter procedure.

For significant valve decisions, a Heart Team brings together the relevant cardiology, imaging and cardiac surgical expertise with your preferences.

Surgical valve repair or replacement

Repair keeps your own valve and corrects the problem where a reliable, lasting repair is possible. Replacement uses an artificial valve when repair is unsuitable or unlikely to last.

Repair can be particularly valuable for selected leaking mitral valves. Replacement may be more appropriate for a heavily damaged, narrowed or calcified valve. If several valves, the aorta or coronary arteries also need treatment, surgery may allow those problems to be addressed together.

Balloon mitral valvotomy: opening a suitable narrowed mitral valve

Balloon mitral valvotomy, or BMV, uses a catheter-mounted balloon to separate fused parts of a narrowed mitral valve. It treats selected cases of rheumatic mitral stenosis without replacing the valve or opening the chest.

Suitability depends on valve shape, flexibility, calcium, associated leakage and whether there is a clot in the left atrium. More than mild mitral leakage, substantial calcification or another problem needing surgery can make BMV unsuitable. Age-related calcific mitral narrowing generally does not respond in the same way as a rheumatic valve with fused leaflets.

BMV can cause complications, including significant leakage, and some patients need surgery. The selection assessment is therefore an essential part of treatment.

Catheter-based replacement or repair

TAVI, also called TAVR, replaces an aortic valve through a catheter. Its principal role is in selected patients with severe aortic stenosis. It does not treat every valve problem.

Selected leaking mitral or tricuspid valves can also be treated using catheter techniques, including edge-to-edge repair, which helps parts of the valve close together. Suitability depends on the anatomy, underlying cause and expected benefit.

Catheter procedures have their own risks and follow-up needs. The choice should include durability, future treatment options and your overall health, rather than being based only on incision size or age.

If my valve needs replacement, why do I need angiography?

An echo assesses your valve and heart function. Coronary angiography checks the arteries supplying blood to the heart muscle. A standard echo cannot reliably exclude important coronary blockages.

Before a valve procedure, checking those arteries may change the treatment plan. For example, significant blockages may mean considering bypass surgery at the same time as valve surgery. Finding a blockage does not automatically mean that you need a stent.

Invasive angiography is not required for every person with a valve diagnosis. The planned intervention, likelihood of coronary disease and previous investigations guide the choice. Coronary CT angiography may be appropriate in selected patients; invasive assessment may be needed when coronary disease is more likely or CT cannot answer the question adequately.

If coronary angiography is advised, ask what the team needs to establish and how the result could change your valve treatment.

Mechanical and tissue valves have different benefits and long-term responsibilities.

TAVI valves are tissue valves. Neither type comes with a guaranteed lifespan. Age, expected longevity, pregnancy plans, ability to manage anticoagulation and future treatment options all belong in the discussion.

Activity advice should fit your condition. Many people can continue normal daily activities, while significant disease may require restrictions or supervised rehabilitation. Ask before starting strenuous exercise if you have severe disease or symptoms.

Keep taking prescribed medicines and attend follow-up after repair or replacement. Treatment improves the valve problem but does not remove the need to monitor the valve and the rest of the heart.

Maintain good dental hygiene and tell your dentist about your valve condition or procedure. Antibiotics before certain dental treatments are recommended for specific high-risk groups, including people with prosthetic valves or certain repair materials, rather than everyone with a valve leak.

If you are planning pregnancy, arrange a review beforehand. Valve severity and anticoagulant treatment can change pregnancy planning and care. Seek advice promptly if you are already pregnant; do not stop prescribed medicines yourself.

You may want help understanding whether your valve problem needs monitoring, whether treatment should happen now, or why repair, replacement, BMV or a catheter procedure has been recommended.

At Sheth Heart Clinic in Bopal, Ahmedabad, Dr. Kulin personally reviews existing reports and images before deciding what further assessment, if any, would help. Bring older studies, your medication list and the proposed treatment plan where available.

A consultation with Dr. Kulin Sheth can help clarify the reason for intervention, alternatives, timing and long-term follow-up. If treatment is urgent or symptoms are unstable, do not postpone emergency care while arranging an elective second opinion.

Seek emergency assessment for sudden severe breathlessness, collapse, persistent chest pain, or possible stroke symptoms such as facial drooping, arm weakness or difficulty speaking. Do not wait for a clinic appointment or WhatsApp response.

New fainting, rapidly worsening exercise tolerance or breathlessness with minimal activity needs prompt assessment, particularly with known severe valve disease. Unexplained fever or chills also needs prompt medical review, especially after valve replacement or repair.
