Mitral and aortic valve endocarditis caused by a rare pathogen: Streptococcus constellatus

Abstract

Streptococcus constellatus endocarditis is associated with systemic embolism and frequently with a poor prognosis. We describe the first case reported in the literature of infective endocarditis by penicillin-resistant S. constellatus causing both mitral and aortic valve regurgitation, treated successfully with double-valve replacement. © 2012 The Author.
