Pacemaker-induced Staphylococcus aureus mitral valve acute bacterial endocarditis complicated by persistent bacteremia from a coronary stent: Cure with prolonged/high-dose daptomycin without toxicity.
Continuous high-grade Staphylococcus aureus bacteremia suggests acute bacterial endocarditis (ABE), a protected focus, ie, an abscess, or a device-related infection. Daptomycin was curative of S. aureus ABE and coronary stent-related bacteremia. Prolonged high-dose daptomycin therapy (12 mg/kg per day for 41 days) is not associated with any toxicity. Persistent S. aureus bacteremia in ABE should suggest myocardial or perivalvular abscess. If intracardiac abscess can be ruled out and there is no extracardiac source of the S. aureus bacteremia, then a device-related infection should be considered.
