Overview
The natural course of tricuspid stenosis is not well defined and it is extremely rare for TS to occur in isolation.[1] The most common cause of TS is rheumatic heart disease and it is usually associated with coexisting mitral valve and/or aortic valve abnormality.[1] TS of rheumatic etiology usually occurs with tricuspid regurgitation. Tricuspid stenosis takes years to develop, with some exceptions such as congenital causes. Complications of tricuspid stenosis include heart failure, liver failure, and stroke.[2]
Natural History
- After several years, the right atrium can become enlarged because blood flow through the narrow tricuspid valve opening is partially blocked. An enlarged atrium can affect the pressure and blood flow in the nearby chambers and veins.
- It can also cause the right ventricle to shrink because the amount of blood entering from the right atrium is reduced. Eventually, less blood circulates through the lungs to get oxygen.
Complication[1][2]
The following complications may occur from tricuspid stenosis:
- Right atrial enlargement
- Atrial fibrillation
- Heart failure
- Infective endocarditis
- Cerebrovascular accident
- Liver failure
Prognosis
With medical intervention, severe tricuspid stenosis appears well tolerated over several years of follow-up.[1]
