Underrecognized pathogen;Staphylococcus warneri‐associated native mitral valve endocarditis in an immunocompetent host: A case report and literature review

Staphylococcus warneri-related endocarditis is rarely reported, raising diagnostic challenges and is often associated with considerable morbidity and mortality. We describe a case of native valve endocarditis caused by S. warneri and complicated by a valve perforation in an immunocompetent patient to raise awareness of this emerging organism.
