Early-onset prosthetic valve endocarditis (EO-PVE) is a serious risk after cardiac valve surgery. Younger patients with multiple positive blood cultures for non-gram-negative bacteria face higher EO-PVE risks.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Cardiac Surgery

Background:

  • Endocarditis is a rare but serious complication following cardiac valve implantation.
  • Prosthetic valve endocarditis (PVE) can occur early after surgery.

Purpose of the Study:

  • To determine the risk and outcomes of early-onset prosthetic valve endocarditis (EO-PVE).
  • Focus on adult patients undergoing cardiac valve implantation.

Main Methods:

  • Retrospective review of a 5-year case series.
  • Identification of bloodstream infections within 60 days of surgery.
  • Utilized a prospective surveillance program.

Main Results:

  • 16 out of approximately 2100 patients (24%) developed EO-PVE.

  • Risk factors included younger age, multiple positive blood cultures, and non-gram-negative organisms.
  • Most EO-PVE cases had recognized wound or catheter infection sources.

    • Conclusions:

    • Patients with multiple positive blood cultures for non-gram-negative bacteria are at risk for EO-PVE.
    • Risk persists even with recognized and treated wound or catheter infections.
    • Early diagnosis and management are crucial for favorable outcomes.
