Tricuspid Valve Stenosis

Causes

Tricuspid valve stenosis is most often caused by the following:

• Endocarditis – This condition occurs when the inner lining of the heart (endocardium) or the heart’s valves become infected by bacteria or other germs.
• Rheumatic fever – This condition results from a rare progression of strep throat that damages the heart valves as the body produces antibodies to fight the strep infection.

Rare causes of tricuspid stenosis can include the following:

• Congenital birth defects
• Systemic lupus erythematosus (SLE), an autoimmune disease
• Right atrial myxoma, a noncancerous tumor in the right side of the heart
• Metastatic tumors
• Chest radiation therapy from cancer treatments
