Tricuspid stenosis


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.

Clinical features:


  1. Symptoms of associated mitral or aortic valve disease.
  2. Symptoms of right heart failure.
  • Abdominal swelling.
  • Hepatic discomfort.
  • Peripheral oedema.
  • Fatigue.


  1. Raised JVP with a prominent ‘a’ wave & a show ‘y’ descent.
  2. Mid diastolic murmur-increased by inspiration.
  3. RHF-hepatomegaly, ascites, peripheral oedema.


  1. Chest X-ray:
  • Enlarged right atrium (non specific for TS)
  1. Echo:
  • Fused, thickened tricuspid valve.
  • Dilated right atrium, Doppler features of TS.


  1. In patients who require surgery to other valve, tricuspid valve is either replaced or subjected to valvotomy at the time of surgery.
  2. Balloon valvuloplasty in rare cases of isolated tricuspid stenosis.
