Surgical intervention for acute bacterial endocarditis is crucial for high-risk patients. Early aggressive surgery improves outcomes, especially for prosthetic valve endocarditis (PVE) and non-streptococcal infections.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Surgical Intervention

Background:

  • Acute bacterial endocarditis presents significant morbidity.
  • While antibiotics are common, a subset of patients requires surgical intervention.

Purpose of the Study:

  • To analyze outcomes of surgical treatment for acute bacterial endocarditis.
  • To identify factors influencing morbidity and mortality in these patients.

Main Methods:

  • Retrospective review of 158 patients undergoing heart valve surgery for acute bacterial endocarditis (1972-1991).
  • Analysis included native valve endocarditis (NVE) and prosthetic valve endocarditis (PVE) subgroups.
  • Outcomes assessed included operative mortality, long-term survival, and recurrent endocarditis rates.

Main Results:

  • Operative mortality was 6% for NVE and 22% for PVE.
  • Ten-year survival was 66% for NVE and 29% for PVE.
  • Prosthetic valve endocarditis and non-streptococcal infections were associated with decreased survival.

Conclusions:

  • Surgical outcomes for acute endocarditis are influenced by infection site, severity, and patient factors.
  • Early, aggressive surgical intervention is recommended to optimize results.
  • Particular attention should be given to patients with non-streptococcal infection or PVE.
