    Pacemaker infections occurred at a 4.2% rate, with Staphylococcus epidermidis being the most common cause. Effective treatment involves removing the infected device and replacing it via a different route.

    Area of Science:

    • Cardiology
    • Infectious Diseases
    • Medical Device Technology

    Background:

    • Pacemaker-related operations carry a risk of infection.
    • Infections can lead to severe complications, including fatality.
    • Understanding infection sources and effective treatments is crucial for patient outcomes.

    Purpose of the Study:

    • To determine the incidence and characteristics of pacemaker-related infections.
    • To identify the causative organisms and potential sources of contamination.
    • To evaluate the effectiveness of current treatment strategies and propose optimal management.

    Main Methods:

    • Retrospective analysis of 546 pacemaker-related operations over a 12-year period.
    • Identification and analysis of 23 infection cases.

  • Microbiological analysis to identify causative organisms.
  • Review of treatment protocols and patient outcomes.

    • Main Results:

    • An infection rate of 4.2% (23 out of 546 operations) was observed.
    • Staphylococcus epidermidis was the most frequent pathogen identified.
    • Infections occurred despite appropriate antibiotic prophylaxis in most cases.
    • Two fatal outcomes were reported among the infected patients.
    • Skin flora was identified as the likely source of contamination.

    Conclusions:

    • Pacemaker infections, though infrequent, pose significant risks.
    • Standard antibiotic prophylaxis may not be fully effective against common pathogens like Staphylococcus epidermidis.
    • Complete removal of infected foreign material and reimplantation via an alternative route is the recommended treatment approach.
