Heart Valve Disease: Types, Symptoms and When Surgery Is Needed

Heart valve disease affects millions of people worldwide and becomes more common with age, yet many people know little about it until a doctor mentions a murmur or a scan reveals a problem. The good news is that valve disease is well understood and highly treatable. This guide explains the types of heart valve disease, the symptoms to watch for, what causes it, and when surgery or a procedure is needed.

What is heart valve disease?

The heart has four valves, the aortic, mitral, pulmonary and tricuspid. They act as one way doors, opening to let blood through and closing to stop it flowing backward. With every heartbeat these valves keep blood moving in the right direction. In heart valve disease, one or more valves stop working properly, which makes the heart work harder and reduces the efficiency of circulation. Over time this strain can damage the heart muscle itself if the problem is not addressed.

The two main types of valve problem

Valve stenosis

Stenosis means a valve has become stiff, thickened or narrowed so it cannot open fully. Blood must squeeze through a smaller opening, forcing the heart to pump harder. The most common and serious example is aortic stenosis, a narrowing of the aortic valve that is especially common in older adults.

Valve regurgitation

Regurgitation, also called a leaky valve or valve insufficiency, means a valve does not close tightly, so blood leaks backward with each beat. The heart then has to pump the same blood twice, which is inefficient and tiring for the muscle. Mitral regurgitation, a leak of the mitral valve, is one of the most common forms.

Some people have both stenosis and regurgitation in the same valve, or problems in more than one valve at once. The exact pattern is identified on an echocardiogram.

Symptoms of heart valve disease

Valve disease often develops slowly, and the body adapts so gradually that people do not realise how much their activity has reduced. Common symptoms include:

• Shortness of breath, especially on exertion or when lying flat
• Fatigue and reduced exercise tolerance
• Swelling of the ankles, feet or abdomen
• Palpitations or an irregular heartbeat
• Dizziness or fainting, particularly with aortic stenosis
• Chest discomfort during activity
• A heart murmur heard by a doctor through a stethoscope

The American Heart Association points out that some people with valve disease have no symptoms for years, which is why a murmur found on examination should always be investigated.

What causes heart valve disease?

There are several causes, and they vary by region and age:

• Age related changes, including calcium buildup that stiffens the valves, the leading cause of aortic stenosis in older adults
• Congenital valve abnormalities, such as a bicuspid aortic valve that a person is born with and that tends to wear out earlier
• Rheumatic heart disease, caused by an untreated streptococcal infection in childhood, still common across South Asia, Africa and the Middle East
• Infective endocarditis, an infection of the heart lining and valves
• Damage after a heart attack or from other heart muscle conditions

How is valve disease diagnosed and staged?

The central test is an echocardiogram, an ultrasound that shows the valves moving and measures how narrowed or leaky they are. Doctors use these measurements to grade the disease as mild, moderate or severe, which guides whether and when treatment is needed. An ECG, chest X ray and sometimes a cardiac catheter study or advanced imaging are added before surgery is planned. If you already have an echocardiogram, a specialist can review it. VNR offers a free review of your cardiac reports with an indicative cost estimate.

When is surgery needed?

Not every valve problem needs an operation. Mild and moderate disease is usually monitored with regular scans, sometimes for many years. Treatment is generally recommended when the disease becomes severe, when symptoms appear, or when scans show the heart is starting to enlarge or weaken under the strain. Acting at the right time, before the heart muscle is permanently damaged, gives the best long term result, which is why regular follow up of known valve disease is so important.

Treatment options

Valve repair

When possible, surgeons prefer to repair your own valve, particularly for leaking mitral valves, because keeping the natural valve has advantages and often avoids lifelong blood thinning medication.

Valve replacement

When a valve is too damaged to repair, it is replaced with a mechanical valve, which is very durable but requires lifelong blood thinners, or a tissue valve, which may not need long term blood thinners but does not last as long. Our page on heart valve replacement and repair explains how the choice is made.

Catheter based and minimally invasive procedures

For selected patients, especially those at higher surgical risk, a narrowed aortic valve can be replaced through a catheter without open surgery. The heart team decides suitability after reviewing your scans and overall health.

What to expect from recovery

Valve surgery is a well established and successful procedure. Patients usually spend a few days in hospital, including some time in intensive care, then recover gradually over several weeks. Most people notice a clear improvement in breathing and energy once the heart no longer struggles against a faulty valve. International patients generally plan to stay in India for a few weeks to cover treatment and early recovery before flying home.

How VNR Medical Service helps international patients

VNR Medical Service helps international patients access expert valve treatment at the NABH accredited DDMM Heart Institute in India, where the cardiac team performs valve repair and replacement. We coordinate your free report review, an indicative cost estimate, medical visa support, travel, treatment and a safe, fit to fly return. To begin, send your echocardiogram for review or contact our coordination team.

Why early treatment of valve disease matters

The heart is remarkably good at compensating for a faulty valve, which is both a blessing and a trap. For years it works harder to make up for the narrowed or leaking valve, and the person may feel only mildly limited. But this extra work comes at a cost. Over time the heart muscle can stretch, thicken and weaken, and once that damage is advanced it may not fully recover even after the valve is fixed. This is why cardiologists monitor valve disease closely and recommend treatment at the right moment, before irreversible strain sets in. Acting at the optimal time, rather than waiting until symptoms are severe, gives the best chance of a full recovery and a return to normal energy and activity. If you have known valve disease, keeping up with your scheduled scans is one of the most important things you can do.
