[Infective endocarditis today; heart surgery in its treatment: how and when].
The authors report the experience of 161 surgical cases operated between 1980 and 1992 because of valve endocarditis. Two hundred and two surgical procedures were performed. Patients were divided into two groups: Group I (EN) considered 117 patients with endocarditis on the native valve; Group II (EP) included 64 patients with prosthetic endocarditis. In 23 patients the prosthesis was implanted for previous endocarditis on the native valve (EP1); in 41 patients the prosthesis was implanted for other valve diseases (EP2). Each group was described according to sex, age, site of endocarditis, previous cardiac diseases, socio-economical level, hemodynamic and infective conditions at surgery, etiology of endocarditis, surgical indication, pathology report, surgical procedure and results. The results were evaluated considering surgical mortality, late mortality and recurrence of endocarditis. The main risk factors were correlated to overall survival and recurrency. Hospital mortality was 7.6% in EN, 13% in EP1, 36.5% in EP2; endocarditis recurrency was 20.3% in EN, 65% in EP1, 19.2% in EP2. Sixteen patients with prosthetic endocarditis were submitted to a second reoperation with 50% mortality; 4 patients to a third reoperation with 50% mortality; 1 patient to a fourth reoperation with no mortality. Actuarial overall survival was 40.3% at 12 years in Group EN, 33.3% at 12 years in Group EP1, 73.4% at 12 years in Group EP2. Finally the Authors report the experience of 12 stentless grafts (autologous, homologous and eterologous) implanted between March 1991 and July 1994 in patients with valve or prosthetic endocarditis with no recurrency at 42 months of follow-up.
