[Surgical treatment of infective endocarditis].
OBJECTIVE
To analyse, retrospectively, 83 patients with infective endocarditis (IE) that were operated during the acute phase of the disease and to identify possible subgroups with distinct mortality.


METHODS
Between 1985 to 1990, 83 patients comprised the subject of this analysis. Fifty-one (61%) were male, aged between 3 months to 71 years, mean of 31.4 +/- 16.7 years.


RESULTS
We could identify two subgroups that were most frequently operated on: the left side IE and the Staphylococcus aureus; and 77 (43%) had left sided IE (p < 0.001). When discriminated accordingly to the specifically etiologic agent (Staphylococcus aureus) this difference continues to be statistically significant: of 29 left sided IE by this agent 13 (45%) were operated on, whereas from 22 right sided IE by the same agents, just 3 (14%) were operated on (p < 0.05). The two major etiologic agents did not show any statistically significant difference in the number of patients that needed to be operated on: on those 51 patients with Staphylococcus aureus IE, 16 (31%) were treated surgically, while from the 60 patients with Streptococcus viridans, 22 (37%) underwent to surgical procedure (p- NS). The mortality in the patients treated by surgery was 32%, and those with Staphylococcus aureus IE were responsible for 46% of the total surgical deaths.


CONCLUSIONS
Surgical treatment were most frequently used in the patient with left sided IE independently of the etiologic agent.
