Rheumatic Heart Disease Management

Introduction

Rheumatic heart disease, often shortened to RHD, is long-term damage to one or more of the heart’s valves caused by an earlier episode (or episodes) of rheumatic fever. Rheumatic fever itself usually follows an untreated or under-treated throat infection with a bacterium called group A streptococcus — the same germ that causes strep throat. Most people who develop rheumatic heart disease had that initial infection in childhood, although the heart problems may not become obvious until many years later.

If you or a family member has been diagnosed with rheumatic heart disease, the focus of care now is no longer on finding out what is wrong. The focus is on protecting the heart from further damage, controlling symptoms, watching the valves over time, and stepping in with procedures or surgery if and when they are needed. This is what doctors mean by “management” — it is not a single treatment but a long-term plan that changes as the disease changes.

This guide explains how rheumatic heart disease is managed today. It covers the medicines used, the role of long-term antibiotic prevention, how valves are monitored, when balloon procedures or valve surgery are considered, what life with RHD looks like, and how the condition is handled in children and during pregnancy. The aim is to help you understand the medical landscape so that conversations with your cardiology team feel clearer and more useful.

What Is Rheumatic Heart Disease?

Rheumatic heart disease is the chronic, structural damage that remains after one or more attacks of acute rheumatic fever. Acute rheumatic fever is an immune reaction: after a streptococcal infection, the body’s defences mistakenly attack its own tissues, including joints, skin, the brain, and most importantly the heart. When the heart is involved, the valves can become inflamed, scarred, thickened, and stiff. The mitral valve (between the left upper and lower chambers) is most commonly affected, followed by the aortic valve. The tricuspid and pulmonary valves are involved less often.

Over time, the damaged valves may stop working properly in two main ways:

• Stenosis — the valve becomes narrowed and stiff, so blood cannot pass through easily.
• Regurgitation — the valve does not close completely, so blood leaks backwards.

Many people have a combination of both in the same valve, or different problems in different valves. The heart then has to work harder to pump blood, which over years leads to enlargement of the heart chambers, irregular heart rhythms such as atrial fibrillation, and eventually heart failure if the valve disease becomes severe.

Rheumatic heart disease is largely preventable. In many high-income countries it has become uncommon because streptococcal throat infections are usually treated early with antibiotics. In parts of South Asia, Africa, the Pacific, and other low- and middle-income regions, however, it remains a leading cause of heart disease in young people. Crowded living conditions, limited access to early antibiotic treatment, and repeated streptococcal infections in childhood all contribute.

Types and Patterns of Valve Involvement

The mitral valve is involved in the great majority of RHD cases.

• Mitral stenosis — the most characteristic lesion of RHD. The valve leaflets thicken and fuse, the opening narrows, and blood backs up behind the valve. This can cause shortness of breath (especially on exertion or when lying flat), fatigue, coughing, and sometimes coughing up small amounts of blood. Atrial fibrillation is common.
• Mitral regurgitation — the leaflets do not close properly, allowing blood to leak back into the upper chamber. It can cause breathlessness, fatigue, and palpitations.
• Mixed mitral disease — both stenosis and regurgitation are present.

Aortic Valve Disease

The aortic valve is the second most commonly affected. Rheumatic aortic regurgitation and rheumatic aortic stenosis can occur alone or together with mitral disease. Aortic stenosis causes chest discomfort, lightheadedness, and breathlessness; aortic regurgitation may be silent for years before causing fatigue and shortness of breath.

Tricuspid and Multi-Valve Disease

The tricuspid valve may be involved directly or may leak as a secondary consequence of severe left-sided disease and raised pressures in the lungs. When more than one valve is affected, this is called multi-valve disease, and it usually means the overall management plan is more complex.

Causes and Risk Factors

The underlying cause of rheumatic heart disease is acute rheumatic fever, which itself follows infection with group A streptococcus. Several factors influence whether someone develops RHD and how severe it becomes.

• Untreated or under-treated strep throat in childhood — a single episode of rheumatic fever can cause valve damage, and repeated episodes substantially increase the risk.
• Recurrent streptococcal infections — each new episode of rheumatic fever can add to the damage already present.
• Age at first attack — rheumatic fever in younger children tends to cause more carditis (heart inflammation) and more long-term valve damage.
• Living conditions — crowded housing, poor ventilation, and limited access to primary healthcare increase the chance of streptococcal spread.
• Family history — some genetic factors may influence susceptibility, although the bacteria and environment are the main drivers.
• Female sex — mitral stenosis from RHD is somewhat more common in women.

For someone who already has RHD, the most important “risk factor” for progression is a further attack of rheumatic fever. This is why preventing recurrence is the cornerstone of long-term care.

Signs and Symptoms to Watch For

If you have been diagnosed with rheumatic heart disease, you are likely already familiar with at least some of its symptoms. The reason to revisit them here is not to teach first-time recognition but to help you notice when things are changing — an early sign that valve disease may be worsening or that a complication is developing.

Symptoms to bring to your cardiology team promptly include:

• New or worsening shortness of breath, especially when lying flat or waking from sleep
• Reduced ability to do activities you previously managed well
• Swelling of the ankles, legs, or abdomen
• Palpitations or an irregular pulse
• Chest discomfort or fainting episodes
• Coughing up blood-streaked sputum
• Sudden weakness, slurred speech, or vision changes (which may suggest a stroke)
• Unexplained fevers that last more than a few days, especially if accompanied by tiredness, weight loss, or night sweats — these can be signs of infective endocarditis, an infection of the valves

Some of these (stroke symptoms, severe breathlessness, fainting, persistent fever with a known valve problem) need urgent medical attention rather than a routine appointment.

Diagnosis and Ongoing Assessment

For most people reading this, the initial diagnosis has already been made. Assessment, however, continues for life because rheumatic heart disease is dynamic — valves can stay stable for many years or can worsen, and the right time for intervention depends on careful tracking.

Echocardiography

Echocardiography (an ultrasound of the heart, often called an “echo”) is the central test for both diagnosing and monitoring RHD. It shows which valves are affected, the type and severity of the lesion, the size and function of the heart chambers, and the pressures in the lungs. The World Heart Federation has published criteria specifically for diagnosing RHD on echocardiography, which doctors use to distinguish definite RHD from borderline findings.

How often echo is repeated depends on disease severity. People with mild valve involvement may be scanned every one to two years; those with moderate or severe disease, or who are pregnant, are usually scanned more often.

Other Tests

• ECG (electrocardiogram) — looks at heart rhythm and chamber enlargement; important for detecting atrial fibrillation.
• Chest X-ray — can show an enlarged heart or fluid in the lungs.
• Blood tests — markers of infection or inflammation, kidney and liver function, and tests to guide anticoagulation when needed.
• Transoesophageal echocardiography (TOE) — an echo done through a probe in the gullet; gives detailed images of the mitral valve and is often used before procedures or surgery.
• Cardiac MRI or CT — sometimes used in complex cases.
• Cardiac catheterisation — an invasive test, used in selected cases to measure pressures inside the heart or to look at the coronary arteries before surgery.

Functional Assessment

How well someone can exercise tells doctors a lot about how the heart is coping. A simple history (“Can you climb a flight of stairs without stopping? Can you walk as fast as your friends?”), a six-minute walk test, or sometimes a formal exercise stress test helps put the imaging findings in context.

Treatment and Management

Management of rheumatic heart disease has several arms, and most patients need a combination of them. The plan is built around three overlapping goals: prevent further rheumatic fever, control symptoms and protect the heart, and intervene on the valves at the right time.

Secondary Prevention: Long-Term Antibiotics

The single most important step in protecting a heart already damaged by rheumatic fever is preventing another attack. This is called secondary prophylaxis and is recommended by the World Heart Federation, the American Heart Association, and the WHO. It usually involves regular doses of penicillin — most commonly an injection of benzathine penicillin G every three to four weeks, although oral penicillin or other antibiotics may be used if injections are not possible or if there is a penicillin allergy.

Decisions about how long to continue prophylaxis depend on age at last attack, the time since the last attack, the severity of valve disease, and the likelihood of further streptococcal exposure. For people with significant valve damage, prophylaxis is often continued for many years — sometimes for life. Stopping it early is one of the main reasons RHD progresses unnecessarily.

Medicines for Symptoms and Heart Protection

Depending on the type and severity of valve disease and on whether heart failure or rhythm problems are present, doctors may prescribe one or more of the following:

• Diuretics — reduce fluid build-up in the lungs and limbs and relieve breathlessness and swelling.
• Beta-blockers — slow the heart rate, which is particularly helpful in mitral stenosis and in atrial fibrillation.
• Rate-controlling drugs such as digoxin or calcium-channel blockers — used in some patients with atrial fibrillation.
• ACE inhibitors, ARBs, or related medicines — used in selected forms of regurgitation and in heart failure.
• Anticoagulants — blood-thinning medicines such as warfarin are recommended for people with atrial fibrillation linked to mitral stenosis, those who have had a stroke or blood clot, and almost everyone with a mechanical valve replacement. Newer direct oral anticoagulants are not currently recommended for rheumatic mitral stenosis or mechanical valves; for those situations, warfarin remains standard.

Doses are individualised, and careful monitoring — particularly of warfarin (INR blood test) — is part of routine care.

Managing Atrial Fibrillation

Atrial fibrillation, an irregular and often fast heart rhythm, is common in rheumatic mitral disease. It worsens symptoms and substantially raises the risk of stroke because clots can form in the upper heart chambers. Management usually includes rate or rhythm control medicines plus anticoagulation. In some cases, procedures to restore normal rhythm (cardioversion or ablation) are considered.

Preventing Infective Endocarditis

Damaged valves are more vulnerable to infection. Good dental hygiene is one of the most important everyday protections, because mouth bacteria can enter the bloodstream during dental work or even from poor oral health. Current guidelines recommend antibiotic prophylaxis before certain dental procedures for people at highest risk, including those with prosthetic valves and certain other conditions. Your cardiologist or dentist can confirm whether this applies to you.

Interventional Procedures and Surgery

When valve disease becomes severe enough to cause significant symptoms or to threaten heart function, doctors consider repairing or replacing the valve. The choice of procedure depends on which valve is affected, the type of damage, the anatomy seen on echo, the patient’s age and overall health, and local expertise.

The main options include:

• Percutaneous balloon mitral valvotomy (also called balloon mitral valvuloplasty) — a catheter-based procedure in which a balloon is passed across a narrowed mitral valve and inflated to open it. It avoids open-heart surgery and gives excellent results in selected patients with rheumatic mitral stenosis whose valves have suitable anatomy on echo.
• Surgical valve repair — possible in some patients, particularly with mitral regurgitation. Repair preserves the patient’s own valve, which has long-term advantages, but is more technically demanding in rheumatic disease because the valve tissue is often thickened and scarred.
• Mechanical valve replacement — a durable artificial valve made from metal and other materials. It lasts a very long time but requires lifelong warfarin therapy to prevent clotting on the valve.
• Bioprosthetic (tissue) valve replacement — a valve made from animal tissue. It does not usually require long-term anticoagulation but wears out over time, particularly in younger patients, and may need re-replacement.
• Multiple-valve surgery — when more than one valve is severely affected, surgery may address several valves at once.

Current AHA/ACC guidelines on valvular heart disease give detailed criteria on the timing of intervention — for example, based on symptoms, valve area or gradient, heart chamber size, pulmonary pressures, and atrial fibrillation. The right time, the right procedure, and the right valve type are decisions made together by the cardiologist, cardiac surgeon, and patient, ideally within a multidisciplinary “heart team”.

Lifestyle and Self-Management

Day-to-day choices have a real effect on how rheumatic heart disease progresses and how well a person feels. The aim is not to live cautiously in fear of the condition but to support the heart that you have.

• Take prophylactic antibiotics on time. Missed injections or doses are one of the commonest reasons valves continue to be damaged.
• Treat sore throats promptly. Any sore throat with fever should be evaluated, particularly in children with a history of rheumatic fever, and treated with antibiotics if streptococcal infection is confirmed or strongly suspected.
• Look after your mouth and teeth. Brush twice daily, floss, and see a dentist regularly. Tell every dentist and doctor about your valve disease.
• Eat a heart-friendly diet. Plenty of vegetables, fruit, whole grains, and lean protein; limited salt, especially if there is heart failure or you take diuretics; and limited processed and very fatty foods.
• Stay active within your limits. Most people with mild to moderate RHD are encouraged to remain physically active. The level and type of exercise should be discussed with your cardiologist, particularly if the disease is more severe.
• Avoid smoking and limit alcohol. Both stress the heart and worsen long-term outcomes.
• Manage other conditions. High blood pressure, diabetes, anaemia, and thyroid problems can all worsen symptoms and need attention.
• Vaccinations. Annual flu vaccination and other vaccinations as advised by your doctor reduce the risk of chest infections that can stress a damaged heart.

Monitoring and Targets

Long-term follow-up usually involves seeing a cardiologist at intervals decided by disease severity. A typical pattern might include:

• Clinical review with history, examination, blood pressure, and rhythm check
• Echocardiography to track valve severity, chamber size, and pulmonary pressures
• ECG and, where relevant, ambulatory rhythm monitoring
• Blood tests including kidney function, electrolytes, and INR if on warfarin
• Review of medications, side effects, and adherence
• Confirmation that secondary antibiotic prophylaxis is up to date

Your team will also watch for “tipping points” — changes that suggest the time for a balloon procedure or surgery is approaching. These include new or worsening symptoms, a fall in heart function, enlargement of the left atrium or ventricle, rising pressures in the lungs, or the onset of atrial fibrillation.

Complications

Even with good care, rheumatic heart disease can cause complications. Knowing what they are helps you and your family recognise them early.

• Heart failure — the heart cannot pump effectively, leading to breathlessness, fatigue, and fluid retention.
• Atrial fibrillation and other arrhythmias — irregular rhythms that increase stroke risk and worsen symptoms.
• Stroke and other clot-related events — clots can form in the left atrium, particularly in mitral stenosis with atrial fibrillation, and travel to the brain or other organs.
• Pulmonary hypertension — raised pressures in the lung arteries due to chronic left-sided valve disease.
• Infective endocarditis — infection of a damaged or prosthetic valve.
• Complications of treatment — for example, bleeding on anticoagulants, or surgical risks of valve replacement.
• Maternal and fetal complications in pregnancy — covered below.

Living with Rheumatic Heart Disease

Rheumatic heart disease is a condition you live alongside, often for decades. For many people, especially those whose disease is mild or moderate and well controlled, day-to-day life looks very much like life without RHD — they work, study, raise families, and remain active. For others, particularly those with more advanced valve disease, adjustments are needed.

Work and Daily Activities

Most work is possible. Very physically demanding jobs, or work in extreme environments, may need to be reviewed with your cardiology team if your valve disease is moderate or severe. Even after valve surgery, many people return to active work.

Exercise and Sport

Regular moderate exercise is generally encouraged in mild disease. In more advanced disease, your cardiologist may suggest avoiding very intense or competitive exertion. After interventions, structured cardiac rehabilitation programmes can help rebuild fitness safely.

Emotional and Social Wellbeing

Living with a long-term heart condition can be stressful. Anxiety about the future, fatigue, and changes in body image after surgery are all common and worth talking about. Family support, peer groups, and professional counselling can help. Children and adolescents with RHD may also need support at school to manage absences for clinic visits and injections.

Pregnancy

Pregnancy puts significant additional demands on the heart, and rheumatic heart disease — especially mitral stenosis — can worsen during pregnancy. Major societies recommend that women of childbearing age with known RHD have pre-pregnancy counselling. This includes assessing valve severity, reviewing medicines (some, including warfarin and certain heart failure drugs, need adjustment), and planning a delivery in a centre with experience of high-risk cardiac obstetrics. With careful planning, many women have successful pregnancies, but the level of monitoring is higher than in the general population.

Rheumatic Heart Disease in Children and Young People

Rheumatic fever usually starts in childhood, and many people with RHD are first diagnosed as children or teenagers. Management in this age group has its own considerations.

Diagnosis at a Younger Age

Active rheumatic fever may show up as joint pains, a rash, a fever, abnormal movements (Sydenham’s chorea), or a heart murmur. After an attack, echocardiography is used to check whether the heart has been involved, and follow-up echos help track whether early valve damage stays stable or progresses.

Antibiotic Prophylaxis in Children

Children diagnosed with rheumatic fever or RHD typically begin regular penicillin prophylaxis straight away, most often as three- to four-weekly injections. This is one of the most important interventions for the long-term health of the heart. The team will work with the family to make injections as comfortable and as predictable as possible.

School, Activity, and Growth

Most children with mild RHD can attend school normally and take part in physical activity. Those with more severe disease may need adjustments to sports, time off for clinic visits, and a school plan that accommodates fatigue. Growth, development, and emotional wellbeing are monitored alongside the heart.

Family Education

Parents and older children are taught to seek medical care for sore throats and fevers, to keep prophylaxis appointments, and to recognise warning signs such as worsening breathlessness or fainting. Siblings of an affected child may also need attention if they have had streptococcal infections.

Transition to Adult Care

As young people grow up, care is gradually handed over from paediatric to adult cardiology services. A planned transition — rather than an abrupt change — reduces the risk of missed prophylaxis or lost follow-up during the teenage and young-adult years, which is a known risk period.

Preventing Progression and Recurrence

Prevention in rheumatic heart disease works at several levels.

• Primary prevention — treating streptococcal throat infections promptly so that rheumatic fever does not happen in the first place. This applies particularly to children and household contacts.
• Secondary prevention — long-term antibiotic prophylaxis to prevent further attacks in someone who already has had rheumatic fever or RHD. This is the most important single step you can take to protect your heart.
• Tertiary prevention — using medical therapy, careful monitoring, and timely procedures or surgery to slow progression and limit complications once valve damage is established.

For most patients, the practical takeaway is simple: keep the antibiotic schedule, attend follow-up appointments, take prescribed heart medicines reliably, and bring any new symptoms to medical attention rather than waiting.

When to Seek Urgent Care

Some changes need same-day or emergency assessment rather than a routine appointment:

• Sudden severe shortness of breath, especially at rest or when lying flat
• Chest pain or pressure
• Fainting or near-fainting
• Sudden weakness or numbness on one side of the body, slurred speech, sudden visual loss, or severe headache — possible stroke
• Coughing up significant amounts of blood
• A persistent fever lasting several days, particularly with tiredness, weight loss, or night sweats, in someone with valve disease or a prosthetic valve — possible infective endocarditis
• Very fast or very irregular heartbeat that does not settle
• Unusual bleeding or bruising if you take warfarin

Frequently Asked Questions

Can rheumatic heart disease be cured?

Valve damage that has already occurred cannot be reversed. However, the disease can be managed very effectively. Antibiotic prophylaxis prevents further attacks, medicines control symptoms, and procedures or surgery can repair or replace damaged valves when needed. Many people live full lives with the condition.

Why do I need penicillin injections for so many years?

Each new episode of rheumatic fever adds further damage to valves that are already affected. Long-term antibiotic prophylaxis — usually penicillin every three to four weeks — greatly reduces the chance of another attack. Major societies including the World Heart Federation and the AHA recommend continuing prophylaxis for years, and often for life in people with significant valve damage.

Do I need antibiotics before dental work?

Some people with rheumatic heart disease — particularly those with prosthetic valves or previous endocarditis — are advised to take a single dose of antibiotics before certain dental procedures. Whether this applies to you depends on your specific situation; your cardiologist and dentist can confirm.

How often will I need an echocardiogram?

The interval depends on how severe your valve disease is. Mild disease may be checked every one to two years; moderate or severe disease may be checked every six to twelve months, or more often if symptoms change, during pregnancy, or after a procedure.

Is balloon valvotomy as good as surgery for mitral stenosis?

In selected patients with rheumatic mitral stenosis whose valve anatomy is suitable on echocardiography, percutaneous balloon mitral valvotomy can give results comparable to surgical valvotomy, while avoiding open-heart surgery. Whether it is suitable for an individual depends on a careful assessment, often including transoesophageal echocardiography.

Mechanical or tissue valve — which is better?

Both have advantages and disadvantages. Mechanical valves are very durable but require lifelong anticoagulation with warfarin and careful INR monitoring. Tissue valves usually do not need long-term anticoagulation but wear out over time, particularly in younger patients, and may need re-replacement. The choice depends on age, lifestyle, pregnancy plans, ability to manage warfarin, other medical conditions, and personal preference, and is discussed in detail with the heart team.

Can I have children?

Many women with rheumatic heart disease have healthy pregnancies, but pregnancy increases the strain on the heart. Pre-pregnancy assessment, review of medicines, and planned care in a centre experienced with cardiac obstetrics are recommended. Some severe forms of valve disease may need treatment before pregnancy is advisable.

Can I exercise and play sport?

Most people with mild or well-treated disease can and should remain active. The level and type of activity should be discussed with your cardiologist if your valve disease is moderate or severe. After valve surgery, cardiac rehabilitation programmes help rebuild fitness safely.

Will my children get rheumatic heart disease?

RHD itself is not inherited. The susceptibility to rheumatic fever may run partly in families, but the main drivers are streptococcal infection and the environment. Treating sore throats promptly in children and addressing crowded living conditions where possible reduces risk.

I feel completely well — do I still need treatment?

Yes. Many people with RHD feel well for long periods even when valve damage is progressing. Continuing prophylactic antibiotics, attending follow-up appointments, and keeping up with monitoring echos are how serious problems are caught early, often before symptoms appear.

Conclusion

Rheumatic heart disease is a chronic condition, but it is not a sentence to a small or fearful life. With consistent secondary antibiotic prophylaxis, good medical therapy, careful monitoring, and well-timed procedures or surgery when needed, the great majority of people with RHD can protect their hearts, manage symptoms, and continue with work, family, study, and many of the activities they value.

The most powerful tools are also the most ordinary: keeping penicillin appointments, treating sore throats promptly, looking after teeth and gums, taking heart medicines as prescribed, and showing up for the next echocardiogram. Around these everyday habits, your cardiology team builds the more specialised parts of care — balloon valvotomy, valve repair or replacement, anticoagulation, rhythm control, pregnancy planning — at the moments when they are most likely to help.

Living with rheumatic heart disease is a long conversation between you, your family, and your medical team. The more clearly you understand each part of that conversation — what the valves are doing, why each medicine matters, what the next decision point looks like — the more confidently you can take part in it.
