It is usually rheumatic in origin and nearly always occurs in associated with mitral and aortic valve disease. Tricuspid valve stenosis is a valvular heart disease which results in the narrowing of the orifice of the tricuspid valve of the heart.It is a relatively rare condition that causes stenosis increased resistance to blood flow through the valve.
Causes: It is almost always caused by rheumatic fever and is generally accompanied by mitral stenosis. Rare other causes include carcinoid syndrome, endocarditis, endomyocardial fibrosis, lupus erythematous, right atrial myxoma and congenitaltricuspid atresia.
- Symptoms of associated mitral or aortic valve disease.
- Symptoms of right heart failure.
- Abdominal swelling.
- Hepatic discomfort.
- Peripheral oedema.
- Raised JVP with a prominent ‘a’ wave & a show ‘y’ descent.
- Mid diastolic murmur-increased by inspiration.
- RHF-hepatomegaly, ascites, peripheral oedema.
- Chest X-ray:
- Enlarged right atrium (non specific for TS)
- Fused, thickened tricuspid valve.
- Dilated right atrium, Doppler features of TS.
- In patients who require surgery to other valve, tricuspid valve is either replaced or subjected to valvotomy at the time of surgery.
- Balloon valvuloplasty in rare cases of isolated tricuspid stenosis.
