[A case report of active prosthetic valve endocarditis caused by MRSA]

A 53-year-old woman, who had undergone MVR and TAP 2 months ago at other hospital, was referred because of PVE caused by MRSA, mediastinitis and remaining AR. Emergency operation was performed, and it was found that mitral mechanical valve was detached and massive vegetation was present around prosthetic valve suture ring. MRSA was cultured from mechanical valve. Thorough debridement for mediastinitis and mitral annulus were performed. Diagnosis and timing of surgical intervention for mechanical PVE were discussed.
