An 86-year-old woman suffering from repeated methicillin-resistant Staphylococcus aureus (MRSA) bacteremia underwent percutaneous lead extraction using an excimer laser. Since negative blood cultures were confirmed three times after lead extraction under intravenous infusion of anti-MRSA drugs, a Micra transcatheter pacing system (Micra TPS) was implanted 7 days after the lead extraction. Although infusion of anti-MRSA drugs was continued for 5 weeks, MRSA was isolated in four separate samples of blood cultures 3 weeks after the discontinuation of the anti-MRSA therapy. The micra TPS was successfully retrieved using a steerable sheath and snare at 8 weeks after implantation.
