BackgroundA few studies have compared mitral valve repair and replacement in the setting of infective endocarditis, with varying results. We compared the characteristics and outcomes of mitral repair and replacement in endocarditis patients.MethodsAll patients undergoing mitral valve repair or replacement for active mitral endocarditis during 2005-2011 were included. Operative and follow-up mortality, composite morbidity, recurrent endocarditis, and redo operations were prespecified endpoints for analyses.ResultsThere were 25 and 35 patients undergoing mitral valve repair and replacement, respectively. They were followed-up for 3.9 ± 2.5 years. Valve replacement patients were older (p = 0.029), had a higher prevalence of intracardiac abscess (p = 0.035), previous endocarditis (p = 0.036), atrial fibrillation (p = 0.001), worse renal function (p = 0.013), higher risk scores (p = 0.004-0.020), and longer operation times (p < 0.001). Repair and replacement had similar rates of operative mortality (4.0% vs. 8.6%, p = 0.634), composite morbidity (16.0% vs. 28.6%, p = 0.357), survival (p = 0.564), recurrent endocarditis (p = 0.081), and redo operations (p = 0.813). Independent predictors of operative mortality were preoperative inotropic or intraaortic balloon pump support. The independent predictor of mortality during follow-up was dialysis. Independent predictors of composite morbidity were intracardiac abscess and hypercholesterolemia. The independent predictor of recurrent endocarditis was previous endocarditis, and the independent predictor of redo operation was previous stroke.ConclusionMitral valve replacement candidates had more baseline risk factors and higher raw rates of postoperative mortality and morbidity, which did not reach statistical significance.© The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
