title: [Pacemaker infection developed one month after the surgery for prosthetic valve endocarditis].
abstract: A 57-year-old man underwent mitral valve replacement and tricuspid annuloplasty for mitral and tricuspid regurgitation. Pacemaker implantation was conducted because of postoperative sick sinus syndrome 2 months after the operation. One year later, the patient was readmitted to the hospital because of high fever. Echocardiography showed 2 vegetations of 10 mm in diameter attached to the mitral mechanical valve. No vegetations were detected on the tricuspid valve or the pacemaker leads. Mitral valve re-replacement was urgently performed under the diagnosis of prosthetic valve endocarditis caused by Staphylococcus aureus. One month after the reoperation, pacemaker infection developed in spite of suitable infection control by daily intravenous injection of sensitive antibiotics. We proceeded to place a temporary pacing wire and extracted the entire permanent pacing system. A new permanent pacemaker was implanted 5 days later. The patient was discharged on the 62th postoperative day without recurrence of infection.
