title: [The effect of timing of surgical intervention on fatality of acute endocarditis].
abstract: Between 1/1986 and 5/1992 a total of 5283 surgical procedures involving extracorporal circulation were performed at our clinic, including 44 patients who underwent a total of 54 operations for acute endocarditis. On the basis of a retrospective study, this paper presents the pre-operative findings and the results of surgery in relation to the duration of the case history. Pathogenic microorganisms were successfully grown from the blood cultures of 63.6% (n = 31) of the patients. Among these microorganisms were viridans streptococci (n = 12), coagulase-negative staphylococci (n = 5), staph. aureus (n = 5), beta-haemolytic streptococci (n = 2) as well as combined infections (n = 2) and miscellanea. Preoperatively, 38 patients were in NYHA stage III or IV. Surgery resulted in an average improvement of 1.6 NYHA classes from NYHA 3.3 to NYHA 1.7. The total-mortality rate was n = 13; early mortality was n = 3. The mean follow-up period was 3.9 years (minimum 5 weeks, maximum 6.4 years). The time elapsed between initial clinical manifestation of the disease and operation had a significant influence on mortality and on the prevalence of complications. Patients who died of endocarditis had a significantly longer case history (p < 0.05). The prognosis was poorer, according to our data, if the case history extended over more than 80 days. Our results demonstrate clearly the necessity for such patients to be referred to a heart surgeon without delay.
