Infection after cardiac device replacement can be serious. Early detection and surgical intervention are crucial for eradicating Staphylococcus epidermidis and resolving complications like patch perforation.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Medical Device Technology

Background:

  • Implantable cardioverter-defibrillator (ICD) replacement is a common procedure.
  • Device-related infections pose a significant challenge in cardiovascular medicine.
  • Staphylococcus epidermidis is a frequent cause of implantable electronic device infections.

Observation:

  • A patient developed unexplained fever and weight loss 12 months post-ICD replacement.
  • Initial antibiotic therapy and infection source investigation were unsuccessful.
  • Exploration revealed Staphylococcus epidermidis in the ICD pocket.

Findings:

  • Recurrent fever post-generator explantation indicated persistent infection.
  • A subsequent operation identified a perforated ICD patch in the right ventricle.

  • Surgical removal of infected patches on cardiopulmonary bypass successfully eradicated the infection.

    • Implications:

    • This case highlights the importance of considering device infection in unexplained systemic symptoms post-replacement.
    • Prompt surgical intervention, including device explantation and debridement, is critical for managing complex ICD infections.
    • Complete eradication of Staphylococcus epidermidis infection required aggressive surgical management beyond antibiotics.
