Микрофлора резецированных клапанов пациентов с инфекционным эндокардитом

Objective. The aim of the study was to perform the retrospective analysis of microflora of heart valves and vessels after reconstructive surgeries. Material and methods. Retrospective study between 2006 and 2011 included microbiological analysis of microflora of heart valves and vessels and hemoculture in 234 patients aged 18-76 years with infective endocarditis. Results. Overwhelming part (89.1%) of 266 exposed valves according to standard method was referred to gram-positive microorganisms. Coagulazonegative staphylococci, enterococci and streptococci were the leading ones among them. Nonenzymatic bacteria and enterobacteria were the most common gram-negative microbes. More than 80% of staphylococci were methicillin-resistant; enterobacteria produced broad spectrum beta-lactamases. Predominant types of streptococci were odontogenous and cariogenous. Hemoculture study showed that valve microflora was the source of diagnosed bacteria in 1/3 of cases. Conclusion. The results confirmed the importance of microflora study of resected valves and hemocultures in patients undergoing surgery in terms of prevention of infectious complications.
