[Analysis of results of surgical treatment of patients with infectious endocarditis].

The results of surgical treatment of 180 patients were studied according to the character of infectious endocarditis (primary--PIE and secondary--SIE), the functional class (FC) in the preoperative period, and the patients' immune status. The survival of patients with PIE (with hospital mortality taken into account) was somewhat higher than that of patients with SIE. Survival in the late-term periods was significantly higher in patients with PIE.
