@entity6331 @entity1 @entity4789 @entity712 @entity340 @entity204
The follow up study on @entity6331 was carried out over a 20 year period by the questionaire method. Two hundreds and seventy-nine @entity1 were analyzed and the following results were obtained. 1) Sixteen cases (5.5%) died, 20 cases (6.8%) showed deterioration, 155 cases (53.1%) were unchanged, 35 cases (12.0%) were improved, 12 cases (4.1%) were announced that their @entity340 disappeared and 22 cases (7.2%) underwent cardiac surgery. The more severe the findings at the final examination under our program, the poorer the courses. 2) The cases having a severe status index showed a tendency for poor prognoses. Mitral steno-regurgitation revealed the poorest prognoses. 3) 84.3 per cent of the living cases were found to be leading normal daily lives without any restriction. 4) The average @entity204 rate was 1.0% per year during the 20 years between 1958 and 1978. The @entity204 rate for age group between 9 and 17 years old was the highest (1.34% per year). 5) The leading cause of @entity204 in every group including all the cases under our program was a recurrence of @entity4789 . However in groups older than 18 years of age chronic @entity712 and unsuccessful cardiac surgery were leading causes.
