Heart & Vascular:


Tricuspid Valve Stenosis or Regurgitation


The tricuspid valve controls blood flow between the right atrium and the right ventricle of the heart. In tricuspid valve stenosis, the valve narrows, increasing pressure in the right atrium and decreasing blood flow to the lungs. In tricuspid regurgitation, the valve does not close entirely, allowing blood to leak backward into the right atrium.

Tricuspid valve disorders are most commonly a result of rheumatic fever (often associated with untreated strep throat or scarlet fever). Other less common causes may include congenital conditions, rheumatoid arthritis or radiation therapy in the chest.

Symptoms of tricuspid regurgitation may include decreased urination, fatigue, swelling in the abdomen, feet or ankles and abnormal pulsing experienced in the neck veins. Symptoms of tricuspid stenosis may include palpitations (rapid, noticeable heart beats), fatigue, neck discomfort and abdominal discomfort.
