17578 Tricuspid Valve Disease

Overview

The tricuspid valve is one of the four valves in your heart. It acts like a door between two of the heart's right-side chambers, helping blood move in the right direction. Tricuspid valve disease means this valve does not open or close properly. It may leak (regurgitation) or become narrow (stenosis).

Tricuspid valve disease is less common than problems with the heart's other valves, such as the mitral or aortic valves. It is more likely to be found in older adults and in people with other long-term heart or lung conditions.

It can affect adults of any age, but it is most often seen in older adults. People with heart failure, high blood pressure in the lungs, a history of rheumatic fever, or a previous heart infection have a higher chance of developing tricuspid valve disease.

Symptoms

Common symptoms

• Feeling very tired or weak
• Shortness of breath, especially with activity
• Swelling in the legs, ankles, or feet
• A fluttering or irregular heartbeat
• Feeling full or bloated in the belly

Symptoms in children

• Poor feeding or getting tired while feeding
• Rapid breathing or breathlessness
• Blue or pale skin, especially on the lips
• In rare congenital cases, these signs are present from birth

Symptoms in older adults

• Increasing shortness of breath with daily activities
• Noticeable swelling in the lower legs or ankles
• A sense of fatigue even after light exertion
• New or worsening irregular heartbeats

Causes

Main causes

• Age-related changes to the valve, often combined with other heart conditions
• Rheumatic fever, an inflammatory disease that can damage heart valves
• Infection inside the heart (endocarditis)
• Enlargement of the right side of the heart from high blood pressure in the lungs or heart failure
• Congenital heart defects, meaning the valve is abnormal from birth

Risk factors

• Heart failure or a history of heart attack
• High blood pressure in the lungs (pulmonary hypertension)
• Previous heart surgery or valve surgery
• Injection drug use, which raises the risk of heart infection
• A history of rheumatic fever or untreated strep infection

When to see a doctor

See a doctor urgently if:

• If you have any of the urgent symptoms listed above, such as worsening breathlessness, rapid weight gain, or a very fast irregular heartbeat, call your doctor or local health service the same day.

Book a routine appointment if:

• If you have ongoing tiredness, ankle swelling, or shortness of breath when active, make a regular appointment to discuss these symptoms.

Diagnosis

Your doctor will start by asking about your symptoms and listening to your heart with a stethoscope. If they suspect a valve problem, they will usually arrange an echocardiogram, which is an ultrasound scan of the heart. This test shows how well the valve is working.

Tests that may be done

• Echocardiogram – an ultrasound of the heart to look at the valve and check blood flow
• Electrocardiogram (ECG) – a recording of the heart's electrical activity
• Chest X-ray – to see the size and shape of the heart
• Cardiac MRI or CT scan – sometimes used for more detailed images
• Blood tests – may be done to check heart, kidney, or liver function

What to expect at your appointment

You may be referred to a cardiologist, a doctor who specialises in heart problems. They will explain the results in plain terms and recommend next steps. Tests are usually painless, and most are done as an outpatient.

Treatment

Treatment depends on the severity of the valve problem and whether it causes symptoms. Many people with mild disease need no treatment other than regular monitoring. Others may need medicines to manage symptoms, and a small number of people may need surgery to repair or replace the valve.

Self-care at home

• Keep a record of your symptoms and report any changes to your doctor
• Monitor your weight regularly if your doctor advises it, to catch fluid build-up early
• Look after your teeth and gums to reduce the risk of bacteria entering your bloodstream
• Avoid smoking and limit alcohol
• Stay physically active in ways that feel comfortable

Medical treatments

Your doctor may prescribe medicines to help your body get rid of extra fluid, relax blood vessels, or make it easier for your heart to pump. These medicines do not fix the valve itself, but they can reduce symptoms. If you have an infection involving the heart, antibiotics are used to treat it. Your doctor may also recommend antibiotics before certain dental or surgical procedures to prevent infection, but only if you are at high risk.

When is surgery considered?

Surgery may be considered if the valve problem is severe and is causing serious symptoms or affecting your heart's function. The operation can involve repairing the valve to make it work better or replacing it with an artificial valve. The choice depends on your age, overall health, and the exact condition of the valve.

Living with this condition

You can usually live a full and active life with tricuspid valve disease. The key is to keep in touch with your healthcare team, take any prescribed medicines, and let them know if symptoms change.

Lifestyle tips

• Stay as active as you are able, and build in rest when you need it
• Eat a balanced diet and avoid added salt to help manage fluid retention
• Manage stress with activities you enjoy, like walking, reading, or spending time with friends
• Keep up with regular dental and medical check-ups

Diet and exercise

A heart-friendly diet is rich in vegetables, fruits, whole grains, lean protein, and healthy fats. Try to limit foods that are high in salt. Regular, moderate exercise such as walking or cycling can help improve your fitness and energy. Ask your doctor for advice on what level and type of activity is safe for you.

Mental health and emotional wellbeing

Living with a heart condition can bring worry, anxiety, or low mood. These feelings are common. Talking to your GP, a counsellor, or a support group can help you cope. Remember that asking for support is a sign of strength, not weakness.

Prevention

You cannot always prevent tricuspid valve disease, but you can lower your risk of some underlying causes. Practising good dental hygiene and treating skin or other infections quickly can help reduce the risk of heart infection. Managing high blood pressure and avoiding intravenous drugs also helps protect your heart.

Vaccines

Keeping your vaccinations up to date, such as flu and pneumonia vaccines if recommended by your doctor, can help prevent respiratory infections that might strain your heart. Ask your local health service which vaccines are advised for you.

Screening programmes

There is no routine screening test for tricuspid valve disease. If you have symptoms or risk factors, your doctor will arrange the appropriate tests.

Complications

If left untreated

• Untreated severe tricuspid valve disease can, over time, weaken the right side of the heart and lead to heart failure
• It can raise the risk of developing an irregular heartbeat, especially atrial flutter or fibrillation
• It can increase the risk of infection on the valve (endocarditis)

Long-term outlook

For most people, tricuspid valve disease develops slowly and can be managed well. Even when the condition is more serious, treatments today are very successful and most people continue to enjoy a good quality of life.
