Total Removal of a Contaminated Pacemaker under Cardiopulmonary Bypass in a Case of MRSA Septicemia / 日本心臓血管外科学会雑誌

ABSTRACT

A 78-year-old man underwent successful removal of a contaminated pacemaker in a case of methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) septicemia. Septicemia was due to a subcutaneous abscess at the site of old cut electrodes. Following debridement of the infected pacemaker pocket, residual leads and the pacemaker system were removed under cardiopulmonary bypass. Bacterial examination of arterial blood and vegetation attached to the leads showed septicemia caused by MRSA. After the operation, antibiotic therapy with vancomycin, arbekacin and minocycline was performed for several weeks. His postoperative course was uneventful without the recurrence of infection. In cases of pacemaker contamination, with septicemia, total removal of the pacemaker system and adequate antibiotic therapy are necessary.
