Daptomycin Failure for Treatment of Pulmonary Septic Emboli in Native Tricuspid and Mitral Valve Methicillin-Resistant Staphylococcus aureus Endocarditis

Abstract EN

Daptomycin has been used with success for the treatment of right-sided methicillin-resistant Staphylococcus aureus (MRSA) endocarditis.

However, its efficacy has not been completely assessed for the treatment of MRSA endocarditis when it is associated with pulmonary septic emboli.

Hereby, we present a case of MRSA mitral and tricuspid native valve endocarditis with pulmonary septic emboli, which was treated with daptomycin as a sole agent, resulting in worsening pulmonary infiltrates and treatment failure.
