Abstract
From 1970 to 1979, 23 patients underwent isolated aortic valve replacement because of active infective endocarditis at our Institution. The main indications for open heart surgery were cardiac failure unresponsive to medical treatment, embolic episodes and septic status. Staphylococci and streptococci were the most frequent offending microorganisms, which could be identified either from blood or valve cultures in 65.2% of the cases. Operative and late mortality was low (4.3 and 4.5% respectively), and postoperative complications rare. The favorable results, probably related to early surgical treatment, and the low incidence of postoperative complications seem to warrant an aggressive approach in the active phases of infective endocarditis involving the aortic valve.
