A Case of Early Prosthetic Valve Endocarditis Caused by Staphylococcus warneri in a Patient Presenting With Congestive Heart Failure

Abstract

Staphylococcus warneri , a coagulase negative staphylococcus, has been isolated in prosthetic device-related infections and has been reported as a rare cause of endocarditis. We report a case of prosthetic aortic valveS. warneriendocarditis, in which the patient lacked typical infectious signs and symptoms, instead presenting with congestive heart failure due to perforation of the valve. Providers should consider endocarditis with a low virulence pathogen such asS. warneriwhen a patient with a prosthetic valve presents with heart failure, even in the absence of fever, leukocytosis and other infectious symptoms.
