From 1972 to 1984, 104 cases of aortic valve @entity166 were treated surgically. The average age of the @entity1 was 40 years and the majority were @entity1 (69/104). Forty @entity1 had no previous @entity299 ; 44 @entity1 had documented @entity340 , which was unlikely in the remaining 20 @entity1 . There were 16 mitral valve, 55 aortic valve, 1 tricuspid, 30 mitro-aortic, 1 mitro-tricuspid and 1 mitro-aorto-tricuspid valve infections. Aerococcus viridans was isolated in only 4 out of 71 positive cultures: the prevalence of the infecting organisms was otherwise normal (30 staphylococcus, 30 streptococcus, 7 rare organisms). Forty one @entity1 were operated because of @entity5122 , 13 for @entity281 and 13 for an association of both indications; 37 @entity1 were operated for @entity887 or threatening vegetations. Eight @entity1 were in functional Class I, 26 in Class II, 52 in Class III and 17 in Class IV. The @entity1 were divided into 4 groups according to the degree of surgical emergency (26 extremely urgent, 26 semi urgent, 32 controlled @entity884 and 20 @entity102 ). The actuarial survival rate was 70% at 5 years. Poor prognostic factors were the presence of previous @entity340 , the isolation of a staphylococcus and an aortic valve localisation. The degree of emergency and the precise surgical indication did not seem to be important. Most @entity1 at long term were in functional Classes I or II. There was no preferential indication for bioprosthetic or mechanical valve replacement in @entity884 .(ABSTRACT TRUNCATED AT 250 WORDS)
