Ceftaroline for the treatment of prosthetic valve endocarditis due to methicillin-resistant Staphylococcus aureus.

The case is described of a frail patient who developed prosthetic valve endocarditis due to methicillin-resistant Staphylococcus aureus (MRSA). Conventional antimicrobial treatments either failed or were contraindicated, and the patient was judged unsuitable for a further valve replacement. A salvage therapy with high doses of a new cephalosporin, ceftaroline, given three times daily was undertaken; subsequently, the patient had not relapsed at two months after completing a six-week course of ceftaroline. Ceftaroline deserves major attention as an alternative choice in difficult-to-treat MRSA endocarditis.
