Characteristics and prognosis of patients requiring valve surgery during active infective endocarditis.
G Fayad, G Leroy, P Devos... - The Journal of heart ..., 2011 - BACKGROUND AND AIM OF THE STUDY: The study aim was to describe the characteristics
and operative mortality of patients requiring valve surgery during active infective endocarditis
(IE). METHODS: This retrospective analysis involved 141 surgically treated patients with ...
This retrospective analysis involved 141 surgically treated patients with active IE. All cardiac operations were performed by the same surgical team between January 1998 and July 2009. All patients had definite (n = 128) or possible (n = 13) endocarditis according to modified Duke criteria. The IE was considered active if surgery was required before completion of a standard course of antimicrobial therapy. Operative mortality included any death occurring within the same hospital admission as surgery.
Among the patients (108 males, 33 females; mean age 56.3 +/- 14.9 years), native valve endocarditis was present in 122 cases (87%). Multiple valve involvement was observed in 27 patients. The infected valves were the aortic (n = 81), mitral (n = 70), tricuspid (n = 15), or pulmonary (n = 2). The most common pathogens were staphylococci (n = 49), streptococci (n = 46) and enterococci (n = 27). The operative mortality was 16%. In univariate analysis, factors linked to operative mortality were age, prosthetic valve endocarditis (PVE) and inadequate antimicrobial therapy. In multivariate analysis, only PVE was an independent adverse predictor (adjusted Odds Ratio = 4.16; 95% confidence intervals 1.14-12.2; p = 0.01).
