Tricuspid Regurgitation


What is tricuspid regurgitation (TR)?

The tricuspid valve is between the right atrium and the right ventricle of your heart. The right atrium pumps blood into your right ventricle. The tricuspid valve opens to direct blood from your right atrium to your right ventricle. It closes when you right ventricle pumps blood to the lungs. TR is when blood flows backwards through the tricuspid valve to the right atrium. This happens because the tricuspid valve does not close properly.

What increases my risk for TR?

TR may be caused by damage to your tricuspid valve. The following can increase your risk for damage:

  • Older age
  • Being born with heart problems
  • Problems in the left side of your heart such as mitral valve prolapse
  • Rheumatic fever or an infection of your tricuspid valve
  • A heart tumor, heart failure, or an abnormal heart beat
  • An injury to your tricuspid valve from chest trauma, a heart procedure, or radiation
  • Use of certain medicines that help you lose weight
  • Severe lung disease, pulmonary artery hypertension, or Marfan syndrome

What are the signs and symptoms of TR?

You may not have symptoms or you may have any of the following:

  • Weakness or fatigue
  • Shortness of breath or getting tired easily during exercise
  • Urinating less than usual
  • Swelling in your abdomen, legs, ankle, or feet
  • Being able to see your neck veins move or pulse

How is TR diagnosed?

Your healthcare provider will examine you. Tell him if you have any heart or lung conditions. Also tell him if you take medicine to help you lose weight. You may also need any of the following:

  • X-ray or MRI pictures may show an enlarged heart or problems with your valve or lungs. You may be given contrast liquid to help the heart and lungs show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
  • An echocardiogram is a type of ultrasound. It is used to show problems with your tricuspid valve and how blood flows through your heart. It may also show how well your heart is pumping. You may need a transthoracic or transesophageal echocardiogram. Ask your healthcare provider about these types of echocardiogram.
  • A stress test helps healthcare providers see how well your tricuspid valve works under stress. Healthcare providers may place stress on your heart with exercise or medicine.
  • A cardiac catheterization is a procedure to check how well your heart is working. It is also used to measure pressure in different parts of your heart. Ask your healthcare provider for more information.

How is TR treated?

Treatment may not be needed if your condition does not cause symptoms. Medicine may be given to decrease swelling and remove extra fluid. Medicine may also be given to treat an infection or decrease pressures in your lungs. The cause of TR, such as lung disease, may need to be treated. Your tricuspid valve may be repaired or replaced if it causes severe symptoms. This may be done through open heart surgery or a heart catheterization.

What can I do to manage my symptoms?

  • Maintain a healthy weight. Being overweight can increase your risk for high blood pressure, diabetes, and coronary artery disease. These conditions can make your symptoms worse. Ask your healthcare provider how much you should weigh. Ask him to help you create a weight loss plan if you are overweight.
  • Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung and heart damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
  • Do not drink alcohol. Ask your cardiologist if it is safe for you to drink alcohol. Alcohol can increase your risk for high blood pressure, diabetes, and coronary artery disease.
  • Eat heart-healthy foods and limit sodium (salt). Eat more fresh fruits and vegetables. Eat fewer canned and processed foods. Replace butter and margarine with heart-healthy oils such as olive oil and canola oil. Other heart-healthy foods include walnuts, whole-grain breads, low-fat dairy products, beans, and lean meats. Fatty fish such as salmon and tuna are also heart healthy. Ask how much salt you can eat each day. Too much salt can cause fluid to buildup in your body. This can increase stress on your heart.
  • Exercise as directed. Exercise can help keep your heart healthy. Ask your healthcare provider what activities are safe for you to do. The amount and type of exercise that is safe may depend on your symptoms. It may also depend on how severe your condition is.
  • Talk to your healthcare provider about pregnancy. If you are a woman and want to get pregnant, talk to your healthcare provider. You and your baby may need to be monitored by specialists during your pregnancy.
  • Ask your healthcare provider if you should take antibiotics before certain procedures. Some procedures may allow bacteria to get into your blood and travel to your heart. This can make your condition worse.
