There are few reports of prosthetic valve endocarditis due to Corynebacterium striatum. Here we report a case of prosthetic valve endocarditis after mitral valve replacement. A 77-year-old woman, who underwent mitral valve replacement and tricuspid valve annulo-plasty 4 months previously, was admitted to our hospital because of shock and loss of consciousness. A transthoracic echocardiogram showed severe mitral regurgitation due to dehiscence of the prosthetic mitral valve. We used the percutaneous cardiopulmonary support system for the management of circulatory collapse and, performed emergency mitral valve replacement. We detected C. striatum in preoperative blood and vegetation cultures. Antibiotic therapy was continued for 6 weeks, and the patients recovered without any complications.
