title: [Etiologic course of heart valve diseases surgically treated during 20 years in France].
abstract: The aim of this study was to analyse the evolution of the aetiologies of operated valvular heart disease over a 20 year period and to assess the consequences. Two thousand five hundred and ninety eight patients who underwent conservative surgery or valve replacement were included. This population was classified according to the date of surgery into 4 groups, each corresponding to a 5 year period. Analysis of these results, especially in the groups operated between 1970 and 1974 and between 1985 and 1989 shows: 1) a change in aetiology: decreased incidence of rheumatic valvular disease (36 versus 61%) and an increased incidence of degenerative lesions (43 versus 23%) (p less than 0.0001); 2) a change in the valvular lesions operated, aortic stenosis has become the commonest operated condition (43 versus 27%) (less than 0.001); 3) an increased age (59 +/- 14 versus 49 +/- 13 years, p less than 0.0001) with a higher proportion of patients over 70 years of age (22 versus 1%, p less than 0.001); 4) a higher incidence of mixed coronary and valvular surgery (11 versus 2%, p less than 0.001).
