Abstract

Although Staphylococcus epidermidis is a frequent cause of prosthetic valve endocarditis (PVE), it is regarded as a rare pathogen of native valve endocarditis (NVE). We report a case of NVE caused by methicillin-resistant S. epidermidis in a 62-year-old man. The bacterium was isolated from blood and tissue culture. The patient underwent valve replacement due to heart failure and was successfully treated by surgery and vancomycin administration for 7 weeks.

Keywords: Staphylococcus epidermidis, Native valve endocarditis

Figure 1

(A) Transthoracic echocardiography shows a vegetation, 1.93 cm×0.59 cm in size, on the aortic valve, (B) a vegetation, 1.96 cm×0.88 cm in size, on the tricuspid valve, (C) and a left-to-right shunt (perimembranous type VSD). RA, right atrium; RV, right ventricle; AV, aortic valve; and VSD, ventricular septal defect.
