Tricuspid Valve Disease

(Tricuspid Regurgitation; Tricuspid Stenosis)

Definition

Tricuspid valve disease refers to damage to the tricuspid heart valve. This valve is located between the atrium (upper chamber) and the ventricle (lower pumping chamber) of the right side of the heart. The tricuspid valve has 3 cusps, or flaps, that control the direction and flow of blood.

The 2 main types of tricuspid valve disease are:

  • Tricuspid stenosis—narrowing of the tricuspid valve
  • Tricuspid regurgitation—backflow of blood into the atrium from the ventricle due to improper closing of the tricuspid valve flaps

Causes    TOP

Rheumatic fever is a common cause of tricuspid valve disease (especially stenosis). Other causes include:

Risk Factors    TOP

A personal history of rheumatic fever may increase your chance of getting tricuspid valve disease.

Symptoms    TOP

In many cases, there are no symptoms. However, if symptoms do occur, they may include:

  • Difficulty breathing
  • Fatigue, especially during physical activity
  • Loss of appetite
  • Abdominal fullness
  • Swelling in the legs or abdomen
  • Changes in skin color

Diagnosis    TOP

You will be asked about your symptoms and medical history. A physical exam will be done. The doctor may be alerted to tricuspid valve disease if you have a heart murmur.

Images may need to be taken to examine your heart. This can be done with:

Your heart's electrical activity may need to be measured. This can be done with electrocardiogram (ECG, EKG).

Your heart's activity during exercise may be measured. This can be done with a cardiac stress test.

Treatment    TOP

If you have mild tricuspid valve disease, your condition will need to be monitored, but may not need treatment right away. When symptoms become more severe, treatments may include:

Medications

Medications may be prescribed to treat specific symptoms associated with tricuspid valve disease. These medications include:

  • Diuretics to promote the production of urine
  • Vasodilators, which dilate blood vessels

Surgery

If tricuspid valve disease is causing severe problems, surgery to repair or replace the valve may be required.

Prevention    TOP

Tricuspid valve disease cannot be prevented. But, there are several things you can do to try to avoid some of the complications:

  • Treat strep throat infections right away to avoid rheumatic fever, which can cause scarring of the heart valve.
  • If your valve problem was caused by rheumatic fever, talk to your doctor about antibiotic treatment to prevent future episodes.
  • Most people with a tricuspid valve defect do not need to take antibiotics to prevent infections before dental or medical procedures. But, there are exceptions. Check with your doctor to see if your condition requires you take antibiotics.
