title: Staphylococcus hominis native mitral valve bacterial endocarditis (SBE) in a patient with hypertrophic obstructive cardiomyopathy.
abstract: There are several species of coagulase-negative Staphylococci (CoNS) that are part of the normal skin flora and are relatively noninvasive/low virulence organisms. CoNS are important pathogens in patients with prosthetic devices and are the most common pathogen associated with prosthetic valve endocarditis. CoNS native valve infective endocarditis (IE) is rare. Patients with hypertrophic obstructive cardiomyopathy and an outflow pressure gradient greater than 30 mm Hg are predisposed to IE. There has been only one reported case of non-mitral valve IE due to CoNS in a patient with hypertrophic obstructive cardiomyopathy. To the best of our knowledge, we report the first case of Staphylococcal hominis mitral valve endocarditis in a patient with hypertrophic obstructive cardiomyopathy.
