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 valveTricuspid regurgitation—backflow of blood into the atrium from the ventricle due to improper closing of the tricuspid valve flaps

A personal history of rheumatic fever may increase your chance of getting tricuspid valve disease.
In many cases, there are no symptoms. However, if symptoms do occur, they may include:
Difficulty breathingFatigue, especially during physical activityLoss of appetiteAbdominal fullnessSwelling in the legs or abdomenChanges in skin color
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 may be prescribed to treat specific symptoms associated with tricuspid valve disease. These medications include: Diuretics to promote the production of urineVasodilators, which dilate blood vessels
If tricuspid valve disease is causing severe problems, surgery to repair or replace the valve may be required.
Tricuspid valve disease cannot be prevented. But, there are several things you can do to try to avoid some of the complications:
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
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.
