Infections of these devices have increased over the last two decades[2] and are associated with an 8.4%-11.6% increased risk of mortality when compared to hospitalizations attributed to noninfectious, cardiac device-related complications[3]. We present a case and literature review of persistent methicillin resistant Staphylococcus aureus (MRSA) septicemia that was found to be secondary to a biventricular ICD infection without any signs of device pocket infection.

Case Report:
An 80 year-old male with coronary artery disease status post coronary artery bypass graft surgery and implantation of a biventricular ICD 15 years ago presented with a 2-d history of fever and abdominal pain.
