Rheumatic Heart Disease

Rheumatic Heart Disease is long-term damage to the heart valves caused by inflammation after rheumatic fever, usually following an untreated or inadequately treated group A streptococcal throat infection. It most often affects the mitral and aortic valves and can be managed effectively when diagnosed early and followed by a heart specialist.

Overview

Rheumatic Heart Disease is a chronic heart condition in which one or more heart valves become scarred, narrowed or leaky after rheumatic fever. Rheumatic fever is an inflammatory reaction that can occur after a group A streptococcal throat infection, especially when the infection is not treated promptly or fully. The immune system response can affect the joints, skin, brain and heart; when the heart valves are damaged, the long-term result is called Rheumatic Heart Disease.

The heart valves act like one-way doors, keeping blood moving in the correct direction through the heart. In Rheumatic Heart Disease, inflammation and scarring can make a valve too tight, called stenosis, or unable to close properly, called regurgitation. The mitral valve is most commonly affected, although the aortic valve and other valves may also be involved.

The condition can affect children, adolescents and adults, and symptoms may not appear until many years after the original episode of rheumatic fever. With early diagnosis, specialist monitoring and appropriate treatment, many people are able to manage symptoms, reduce complications and maintain a good quality of life.

Symptoms

Rheumatic Heart Disease symptoms vary depending on which valve is affected and how severe the valve narrowing or leakage is. Some people have no symptoms at first, and the condition is found because a doctor hears a heart murmur during an examination. Others may develop symptoms gradually as the heart works harder to pump blood efficiently.

Common symptoms can include shortness of breath during activity or when lying flat, unusual tiredness, reduced ability to exercise, palpitations, chest discomfort and swelling in the ankles, feet or abdomen. Some people may notice a persistent cough, dizziness or a fast or irregular heartbeat. Children may have poor weight gain, fatigue during play or difficulty keeping up with peers.

Symptoms can also relate to complications of valve disease, such as heart rhythm problems or heart failure. A person should not assume that breathlessness or tiredness is simply due to age, stress or poor fitness, particularly if there is a history of rheumatic fever, repeated sore throats or known heart murmur. A medical assessment can clarify the cause and guide safe care.

Causes & Risk Factors

Rheumatic Heart Disease is caused by rheumatic fever, which is an immune-mediated inflammatory illness that may follow infection with group A streptococcus bacteria, most often in the throat. The bacteria do not usually infect the heart valves directly. Instead, the body’s immune response can mistakenly affect heart tissue, leading to inflammation and later scarring of the valves.

Not everyone who has a streptococcal throat infection develops rheumatic fever, and not everyone with rheumatic fever develops Rheumatic Heart Disease. Risk is higher when sore throats caused by group A streptococcus are not diagnosed or treated, when there are repeated infections, or when access to healthcare is limited. Crowded living conditions and childhood or adolescent age can also increase exposure to streptococcal infection.

• Previous rheumatic fever is the strongest risk factor for Rheumatic Heart Disease.
• Recurrent rheumatic fever episodes can cause further valve damage.
• Family and community factors may influence exposure and access to early treatment.
• Pregnancy can reveal previously unnoticed valve disease because the heart works harder during pregnancy.

Prevention focuses on prompt assessment of significant sore throat symptoms, appropriate antibiotic treatment when a streptococcal infection is confirmed or strongly suspected, and long-term prevention of recurrent rheumatic fever in people who have already had it.

Diagnosis

Diagnosis begins with a careful medical history and physical examination. A doctor may ask about previous rheumatic fever, repeated sore throats, joint pain, fever, skin changes, fainting, breathlessness, palpitations or known heart murmurs. During examination, the doctor listens for murmurs and signs that the heart or lungs are under strain.

Echocardiography, an ultrasound scan of the heart, is the main test used to diagnose and assess Rheumatic Heart Disease. It shows the structure and movement of the valves, measures narrowing or leakage, and checks how well the heart chambers are working. Echocardiography can detect valve changes even before symptoms become obvious.

Additional tests may include an electrocardiogram to check heart rhythm, a chest X-ray to assess heart size and lung congestion, and blood tests to look for inflammation or evidence of recent streptococcal infection. In more complex cases, advanced imaging or cardiac catheter-based tests may be used by specialists to plan treatment.

Because treatment decisions depend on valve severity, heart function, symptoms and overall health, diagnosis is best managed by a cardiologist or a team experienced in valve disease. Regular follow-up tests help track whether the valve problem is stable or progressing.

Treatment Options

Treatment for Rheumatic Heart Disease is individualized. The right approach is decided by a specialist after assessing symptoms, echocardiogram findings, heart rhythm, valve severity, age, pregnancy plans, other health conditions and the risk of recurrent rheumatic fever. The goals are to prevent further valve damage, control symptoms, reduce complications and improve long-term heart function.

Medical treatment may include long-term antibiotic prevention for people with a history of rheumatic fever, as recommended by national or international guidelines. Other medicines may be used to reduce fluid buildup, support heart function, control blood pressure or manage abnormal heart rhythms. Some patients with certain rhythm problems or valve conditions may need blood-thinning treatment to reduce clot risk, under close medical supervision.

When valve disease becomes severe, a procedure may be considered. Depending on the valve and the type of damage, options can include catheter-based treatment to widen a narrowed valve, surgical valve repair or surgical valve replacement. The choice depends on valve anatomy, the person’s age and health, local expertise and the expected benefits and risks.

Supportive care is also important. This can include regular cardiology follow-up, dental and infection-prevention advice, rehabilitation or supervised activity guidance, and specialist counseling before pregnancy. People should not start, stop or change medicines without medical advice, because valve disease and heart rhythm conditions require careful monitoring.

Living With / Prognosis

Many people with Rheumatic Heart Disease live active lives, especially when the condition is found early and followed regularly. Prognosis depends on the number of valves affected, the severity of narrowing or leakage, heart function, rhythm problems, response to treatment and whether recurrent rheumatic fever is prevented. Regular check-ups are essential because valve disease can change slowly over time.

Daily living often includes learning to recognize symptom changes, taking prescribed prevention or heart medicines consistently, attending echocardiogram appointments and discussing safe activity levels with a clinician. A heart-healthy lifestyle, including not smoking, maintaining a balanced diet, staying physically active within medical advice and managing blood pressure, supports overall cardiovascular health.

Pregnancy needs special planning in women with Rheumatic Heart Disease because pregnancy increases the workload on the heart. Pre-pregnancy assessment by cardiology and obstetric specialists can help identify risks, adjust medicines safely and plan monitoring. People with prosthetic valves or complex valve disease may need more specialized follow-up.

For international patients who need evaluation or treatment, Acibadem International offers access to multidisciplinary cardiology and cardiac surgery teams in JCI-accredited hospitals. Care should always be based on a specialist assessment and clear discussion of suitable options.

When to See a Doctor

A person should see a doctor if they have symptoms such as shortness of breath, palpitations, chest discomfort, unexplained fatigue, swelling of the legs or a newly detected heart murmur. Medical review is also important for anyone with a history of rheumatic fever, known valve disease or repeated untreated sore throats during childhood or adolescence.

Children and teenagers should be assessed for significant sore throat symptoms, especially when accompanied by fever, swollen neck glands, headache, abdominal pain or absence of cough. Prompt diagnosis and appropriate treatment of streptococcal throat infection can reduce the risk of rheumatic fever. Families should also seek care if a child develops joint swelling, unusual movements, rash or chest symptoms after a sore throat.

Urgent medical attention is needed for severe breathlessness, fainting, sudden weakness or numbness on one side of the body, difficulty speaking, severe chest pain, coughing pink frothy sputum or a very fast irregular heartbeat with dizziness. These symptoms can have several causes, but in someone with valve disease they should be assessed quickly and calmly by qualified medical professionals.

Frequently asked questions

What is Rheumatic Heart Disease?

Rheumatic Heart Disease is permanent or long-term damage to the heart valves after rheumatic fever. Rheumatic fever is an inflammatory reaction that can follow a group A streptococcal throat infection. The condition most often affects the mitral valve and can cause valve narrowing, leakage or both.

Is Rheumatic Heart Disease the same as rheumatic fever?

No. Rheumatic fever is the earlier inflammatory illness that can affect several parts of the body, including the heart. Rheumatic Heart Disease is the lasting valve damage that may remain after one or more episodes of rheumatic fever.

Can Rheumatic Heart Disease be prevented?

Many cases can be prevented by timely diagnosis and treatment of streptococcal throat infections and by preventing recurrent rheumatic fever in people who have already had it. Prevention plans should be guided by a doctor and may include long-term antibiotic prophylaxis. Good access to primary healthcare and follow-up is important.

How is Rheumatic Heart Disease diagnosed?

Diagnosis is based on medical history, physical examination and heart imaging. Echocardiography is the key test because it shows valve structure, valve leakage or narrowing and heart function. Additional tests may check heart rhythm, heart size and signs of recent infection or inflammation.

Does Rheumatic Heart Disease always require surgery?

No. Some people need monitoring and medicines, while others may need a catheter-based procedure or valve surgery if disease is severe. The decision depends on symptoms, valve findings, heart function and overall health. A cardiologist or heart valve team should decide the safest approach after assessment.

Can a person with Rheumatic Heart Disease exercise?

Many people can be physically active, but the safe level of exercise depends on valve severity, symptoms and heart rhythm. A cardiologist can advise whether normal activity, modified exercise or supervised rehabilitation is appropriate. New breathlessness, chest discomfort or dizziness during activity should be reviewed by a doctor.

Can women with Rheumatic Heart Disease have a healthy pregnancy?

Many women with mild or well-managed valve disease can complete pregnancy with specialist monitoring. However, pregnancy increases the workload on the heart, so assessment before conception is strongly recommended. Cardiology and obstetric teams can review valve severity, medicines and the safest monitoring plan.
