[Emergency surgical treatment of infectious endocarditis. Experience developed on 19 consecutive cases]

Our experience with the emergency surgical treatment of 19 consecutive cases of infective endocarditis (IE) is reported. The aortic valve was always affected, either alone (n = 16) or together with the mitral valve (n = 3). All patients were male. In 10 cases it was possible to identify the infecting agent (a staphylococcus was found in 6). Congestive heart failure (CHF) was the principal indication for surgery in 14 cases (in 6 active IE was associated). Five patients (1 with CHF) underwent operative treatment because of systemic emboli. Fifteen patients were in New York Heart Association (NYHA) functional class IV, 3 in class III and 1 was in class II. Two patients (10.5%), both operated on for CHF, died in the early postoperative period. Early prosthetic valve dehiscence occurred in 2 cases, reoperation was successful in both. Follow-up of operative survivors ranges between 7 and 108 months (mean = 53.24 +/- 41.89). One patients died 10 months after operation with CHF following late prosthetic dehiscence. Out of 16 currently surviving patients 14 are in NHYA functional class I, 1 is in class II and 1 in class III. No one of them has had relapse of IE.
