title: [Prognosis of surgically treated infectious endocarditis].
abstract: The prognostic factors in infective endocarditis patients who underwent surgery in the acute stage were evaluated from the records of 189 cases of native valve endocarditis operated upon between 1970 and 1986. Surgery had been performed before June 30, 1982 in 105 patients (group 1) and since July 1, 1982 in 84 patients (group 2). Group 2 only differed from group 1 in that the proportion of negative blood cultures was lower (13.7% vs 35%; p less than 0.01) and that of subjects older than 70 was higher (11.6% vs 5.7%; p less than 0.01). 105 patients (66 in group 1, 39 in group 2) had been operated upon during the first 6 weeks of antibiotic therapy ("early surgery"), while 84 patients (57 in group 1, 27 in group 2) had been operated upon between 7 and 24 weeks from the beginning of antibiotic therapy ("semi-early surgery"). Hospital mortality was 23.6% in group 1 (29/123) as against 10.6% in group 2 (7/66; p less than 0.05). The difference in mortality between the two groups was significant only in early surgery patients (33.3% vs 7.7%; p less than 0.01) and in patients operated upon while the infection was active with presence of pathogens in valve cultures (47.4% vs 7.7%; p less than 0.05). A study of mortality factors showed that the operative prognosis did not depend on the type of valve replacement performed or on the pathogen involved, but solely on the degree of cardiac failure before surgery. The post-hospital course was evaluated in group 1 patients followed up during 61.8 months on average.(ABSTRACT TRUNCATED AT 250 WORDS)
