Rheumatic heart disease is a sequel of rheumatic joint disease. rheumatic joint disease usually follow untreated or inadequately treated sore throat and tonsillitis mostly in the childhood.
Most commonly affected is the valve between the two chambers of left side heart, called the mitral valve. The valve gets deformed creating blood flow disturbances through it to the left ventricle.
Gradually, there occurs back pressure changes and the function of many other chambers of heart deteriorate. As a result there occurs;
  • Breathlessness,
  • Puffiness of face,
  • swelling of both the legs and feet; and spreads to other parts of body,
  • Day to day work becomes difficult.
  • infections in the chest may occur.
There is usually a history of childhood attack of rheumatic joint disease; it is said that, "Rheumatic arthritis affects joints first first, then leaves joins and bites the heart."
Now-a-days, incidence of this disease is decreasing due to liberal use of antibiotics to treat childhood throat infections. Moreover, diagnosed rheumatic arthritis are also being treated adequately.
Dilation of the mitral valve and replacement whenever required are available for established disease.
