The surgical treatment of infective endocarditis

Authors:

Abstract
We have reviewed 108 cases of bacterial endocarditis treated surgically since 1968. The mean age of the patients was 47.7±15.6 years (± SD) (range, 14–79 yr). Seventy‐seven percent were male. The most common causative organisms were staphylococci (46%), streptococci viridans group (25%), and other streptococci (20%). Forty‐five percent, 25%, and 13% of patients had native aortic valve, native mitral valve, or native double valve (AV/MV) involvement, respectively. Eighteen patients had prosthetic valve endocarditis. No patient underwent surgery for tricuspid valve endocarditis. Seventy‐three patients were considered to have active endocarditis (AE) (positive blood or tissue cultures and/or annular abscesses). The 35 remaining patients had healed endocarditis (HE). Preoperative complications in patients with either AE or HE were stroke (11%, 11%), renal failure (33%, 3%;pppp (pppp.
