Heart Valve Disease

Heart Valve Disease is a condition in which one or more of the heart’s valves do not open fully, close properly, or both, which can disturb normal blood flow through the heart. It may develop slowly over many years or appear suddenly, and treatment depends on the affected valve, severity, symptoms and overall heart health.

Overview

Heart Valve Disease, also called valvular heart disease, occurs when one or more of the four heart valves do not work normally. The heart valves act like one-way doors, keeping blood moving in the correct direction through the heart and onward to the lungs and body. When a valve becomes too narrow, too leaky, or both, the heart may have to work harder to pump blood effectively.

The four heart valves are the aortic, mitral, pulmonary and tricuspid valves. Valve disease most often affects the aortic or mitral valve, although any valve can be involved. A valve may become narrowed, known as stenosis, which limits forward blood flow. It may also leak, known as regurgitation or insufficiency, allowing blood to flow backward.

Heart Valve Disease can be present from birth or develop later in life due to aging, infection, heart muscle changes or other medical conditions. Some cases remain mild and stable for many years, while others progress and cause symptoms or strain on the heart. With careful diagnosis and follow-up, many people receive effective monitoring, medical treatment, valve repair or valve replacement when needed.

Symptoms

Symptoms of Heart Valve Disease vary depending on which valve is affected, whether the valve is narrowed or leaking, and how quickly the problem develops. Mild valve disease may cause no symptoms and may be discovered only when a doctor hears a heart murmur during a routine examination. In other people, symptoms appear gradually and may be mistaken for normal aging or reduced fitness.

Common symptoms can include shortness of breath during activity or when lying flat, unusual fatigue, reduced ability to exercise, chest pressure or discomfort, and a fast, fluttering or irregular heartbeat. Some people experience dizziness, fainting, swelling of the ankles, feet or abdomen, or unexplained weight gain from fluid retention.

• Aortic valve disease may cause chest discomfort, breathlessness, dizziness or fainting, especially with exertion.
• Mitral valve disease may cause fatigue, shortness of breath, palpitations or fluid build-up.
• Tricuspid or pulmonary valve disease may cause swelling, abdominal fullness, fatigue or signs of right-sided heart strain.

Symptoms can be intermittent, and their severity does not always match the seriousness of the valve problem. Any new or worsening shortness of breath, chest discomfort, fainting, or swelling should be assessed by a qualified doctor, particularly in someone with a known heart murmur or previous valve diagnosis.

Causes & Risk Factors

Heart Valve Disease has many possible causes. Some people are born with valves that are formed differently, such as a bicuspid aortic valve, where the aortic valve has two leaflets instead of the usual three. Congenital valve differences may not cause symptoms in childhood but can become important later in life if the valve narrows or leaks.

Acquired valve disease can develop with aging, calcium build-up on valve tissue, previous heart infection, rheumatic fever, heart attack, cardiomyopathy or long-standing high blood pressure. Infection of the inner lining of the heart, called infective endocarditis, can damage valves and requires urgent medical care. Changes in the heart’s size or shape can also prevent a valve from closing properly, especially the mitral or tricuspid valve.

Risk factors include older age, a history of heart murmur, congenital heart disease, previous rheumatic fever, previous endocarditis, chronic kidney disease, radiation treatment to the chest, and certain connective tissue or inflammatory conditions. Lifestyle-related cardiovascular risk factors, such as smoking, high blood pressure, diabetes and high cholesterol, may contribute to overall heart disease and should be managed as part of long-term heart care.

Not every risk factor can be changed, but regular medical follow-up can identify valve problems early and monitor whether they are progressing. People with known valve disease may also need specific advice about dental health, infection prevention and safe exercise from their cardiology team.

Diagnosis

Diagnosis of Heart Valve Disease begins with a medical history, physical examination and careful listening to the heart with a stethoscope. A heart murmur can suggest turbulent blood flow across a valve, but a murmur alone does not confirm the severity of valve disease. The doctor will ask about symptoms, exercise tolerance, previous infections, family history and other heart conditions.

Echocardiography, an ultrasound scan of the heart, is the main test for evaluating heart valve structure and function. It can show whether a valve is narrowed or leaking, how well the heart chambers are pumping, and whether the heart has enlarged or developed increased pressure. In some cases, a transesophageal echocardiogram, performed with an ultrasound probe placed in the esophagus, provides more detailed images.

Other tests may be used depending on the situation. An electrocardiogram can check heart rhythm and signs of heart strain. A chest X-ray may show heart enlargement or fluid in the lungs. Cardiac MRI, cardiac CT, exercise testing or cardiac catheterization may help clarify anatomy, severity or treatment planning, especially before a valve procedure.

Valve disease is usually graded by severity, often as mild, moderate or severe, using several measurements rather than one result alone. This grading helps specialists decide whether monitoring is appropriate or whether treatment should be considered. Follow-up intervals depend on valve type, severity, symptoms and overall heart function.

Treatment Options

Treatment for Heart Valve Disease depends on the affected valve, the type of problem, severity, symptoms, heart function, age, general health and personal circumstances. The right approach is decided by a specialist after assessment, often by a multidisciplinary heart valve team for more complex cases. Treatment may range from regular monitoring to medication, catheter-based procedures or heart valve surgery.

For mild or stable valve disease, active surveillance may be the safest approach. This usually includes periodic cardiology visits, repeat echocardiograms, symptom review and management of related conditions such as high blood pressure, rhythm disorders or heart failure symptoms. Medicines cannot usually repair a damaged valve, but they may help relieve symptoms, control blood pressure, manage fluid build-up, support heart rhythm control or reduce clotting risk in selected situations.

When valve disease is severe, progressive or causing heart strain, a procedure may be recommended. Some valves can be repaired, preserving the person’s own valve tissue. In other cases, valve replacement may be needed using a mechanical or biological valve. Procedures may be performed through open-heart surgery or, for selected patients and valve types, through less invasive catheter-based techniques.

• Medication may be used to manage symptoms and associated heart conditions.
• Valve repair aims to restore better valve function when anatomy is suitable.
• Valve replacement may be considered when repair is not possible or not the best option.
• Catheter-based procedures may be appropriate for selected patients after specialist evaluation.
• Cardiac rehabilitation can support recovery, safe activity and long-term heart health after treatment.

Decisions about timing are important. Treating too early may expose a person to unnecessary procedural risk, while waiting too long may allow heart damage to progress. For this reason, people with significant valve disease should be followed by clinicians experienced in valvular heart disease.

Living With / Prognosis

Many people with Heart Valve Disease live active lives, especially when the condition is diagnosed early and monitored appropriately. Prognosis depends on the valve involved, severity, symptoms, heart function, other medical conditions and whether treatment is needed. Mild valve disease may remain stable for long periods, while severe valve disease often requires specialist treatment to protect heart function.

Daily life with valve disease often includes paying attention to symptoms and maintaining general cardiovascular health. A doctor may recommend suitable physical activity, a heart-healthy diet, blood pressure control, not smoking, weight management and treatment of diabetes or cholesterol problems. People should ask their doctor what level of exercise is safe, particularly if they have severe valve disease, symptoms, rhythm problems or reduced heart function.

Good dental hygiene and regular dental care are important because bacteria from the mouth can sometimes enter the bloodstream and infect heart valves. Some people at higher risk may need special preventive measures before certain procedures, but this decision should be made by a doctor or dentist based on current guidance. Patients with artificial valves or previous valve infection should make sure all healthcare providers know their history.

After valve repair or replacement, follow-up remains essential. People may need imaging tests, rhythm checks, medication review and guidance about activity, travel and future procedures. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat heart valve disease for international patients, with care plans based on individual assessment.

When to See a Doctor

A person should see a doctor if they develop symptoms that may suggest Heart Valve Disease, such as shortness of breath, unusual tiredness, chest discomfort, palpitations, dizziness, fainting or swelling in the legs or abdomen. Medical advice is also important if a heart murmur has been detected, even when there are no symptoms, because an echocardiogram may be needed to clarify the cause.

People already diagnosed with valve disease should contact their healthcare provider if symptoms appear, become more frequent or limit normal activities. Changes such as needing more pillows to breathe comfortably at night, waking breathless, reduced exercise capacity or new ankle swelling can indicate that the heart is under strain.

Urgent medical assessment is needed for severe chest pain, fainting, sudden severe shortness of breath, symptoms of stroke, or signs of a serious infection such as fever with chills in someone with known valve disease or an artificial valve. These symptoms do not always mean a valve emergency, but they should be assessed promptly and safely.

Routine follow-up is just as important as urgent care. Regular monitoring helps doctors detect progression before complications develop and allows timely discussion of treatment options if the valve problem becomes more significant.

Frequently asked questions

What is Heart Valve Disease?

Heart Valve Disease is a problem with one or more valves inside the heart. A valve may be too narrow, may leak, or may have both problems, which can affect how blood flows through the heart. Some people have no symptoms at first, while others develop breathlessness, fatigue, chest discomfort or swelling.

Is Heart Valve Disease serious?

Heart Valve Disease can be mild, moderate or severe. Mild disease may only need regular monitoring, while severe disease can strain the heart and may require a procedure or surgery. A cardiologist can determine seriousness using symptoms, examination findings and echocardiography.

What are the early symptoms of Heart Valve Disease?

Early symptoms may include getting tired more easily, shortness of breath with activity, palpitations, lightheadedness or reduced exercise capacity. Some people do not notice symptoms until the disease has progressed. A heart murmur found during a routine examination may be the first sign.

Can Heart Valve Disease be treated without surgery?

Some people can be managed with monitoring, lifestyle measures and medication to control symptoms or related heart conditions. However, medicines usually do not correct a severely damaged valve. If the valve problem becomes severe or affects heart function, a specialist may discuss valve repair, replacement or catheter-based options.

How is Heart Valve Disease diagnosed?

The main diagnostic test is an echocardiogram, which uses ultrasound to show the valves, heart chambers and blood flow. Doctors may also use an electrocardiogram, chest X-ray, cardiac CT, cardiac MRI, exercise testing or catheterization in selected cases. The choice of tests depends on symptoms and the suspected valve problem.

Can a person exercise with Heart Valve Disease?

Many people with mild or well-controlled valve disease can exercise safely, but the right level of activity should be discussed with a doctor. People with severe valve disease, symptoms, fainting, chest discomfort or rhythm problems need individualized advice. A cardiologist or cardiac rehabilitation team can help plan safe activity.

What happens after heart valve repair or replacement?

After a valve procedure, follow-up care is needed to check valve function, heart rhythm, healing and medications. Some people may need cardiac rehabilitation and long-term imaging surveillance. The exact follow-up plan depends on the type of procedure, the valve involved and the person’s overall heart health.
