Emergency heart valve replacement for acute bacterial endocarditis showed a 21% operative mortality. Survivors had no significant complications, supporting early surgery for high-risk patients.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Surgical Innovation

Background:

  • Bacterial endocarditis poses a significant risk, often necessitating urgent intervention.
  • The role of emergency heart valve replacement in severe cases remains a critical area of study.

Purpose of the Study:

  • To evaluate the outcomes of emergency heart valve replacement in patients with acute bacterial endocarditis.
  • To identify risk factors associated with unfavorable prognosis in these patients.

Main Methods:

  • A retrospective analysis of 14 patients undergoing emergency heart valve replacement for acute bacterial endocarditis over 12 years.
  • Assessment of operative mortality, postoperative complications, and identification of prognostic indicators.

Main Results:

  • Operative mortality was 21% (3/14).
  • No significant postoperative periprosthetic regurgitation or reinfection was observed in survivors.
  • Virulent pathogens, previously normal valves, acute aortic insufficiency with mitral valve premature closure, and floating vegetations were identified as risk factors.

Conclusions:

  • Early surgical intervention is effective for bacterial endocarditis patients with unfavorable etiology or complicated courses.
  • Emergency heart valve replacement can be a life-saving procedure with acceptable outcomes in selected high-risk patients.
