[Some problems in rheumatic valvular defects]

The post-mortem examined rheumatic valvular diseases are confronted for the period 1961-1967 and 1968-1973. Advanced age with one decade is established in the deceased during the second period, as well as increased per cent of thromboembolic complications and chronic cardiac insufficiency and decreased per cent of rheumatic activity. A considerable per cent of rheumatic activity is observed in the deceased during the fourth and fifth decade. No difference concerning sex and valvular lesions are established in both groups.
