Infective endocarditis (IE) in children is linked to congenital heart defects, with bacterial causes shifting over time. Treatment strategies vary based on the causative agent and valve status, emphasizing medical management when possible.

Area of Science:

  • Pediatric Cardiology
  • Infectious Diseases
  • Cardiovascular Surgery

Background:

  • Infective endocarditis (IE) in children is predominantly associated with congenital structural heart lesions, particularly septal defects.
  • The incidence of IE linked to rheumatic heart disease has significantly decreased over the last two decades.
  • Nosocomial catheter-associated bacteremia is an emerging risk factor for IE, especially in infants.

Purpose of the Study:

  • To review the current landscape of infective endocarditis in pediatric populations.
  • To outline the changing etiologies and common causative agents of IE in children.
  • To discuss contemporary management strategies and antibiotic regimens for pediatric IE.

Main Methods:

  • Review of recent literature and clinical data on pediatric infective endocarditis.

  • Analysis of trends in causative microorganisms and associated cardiac conditions.
  • Evaluation of current therapeutic approaches, including medical and surgical interventions.
  • Main Results:

    • Congenital heart defects remain the primary predisposing factor for IE in children.
    • Streptococci are the most common cause of IE in natural valves, while staphylococci and Gram-negative rods are more frequent in nosocomial infections.
    • Medical management is often successful, with surgical intervention reserved for cases of clinical or microbiological failure.

    Conclusions:

    • The etiology of pediatric IE has evolved, with a decline in rheumatic heart disease and an increase in catheter-associated infections.
    • Appropriate antibiotic selection, guided by causative agents and susceptibility, is crucial for successful treatment.
    • Further research is needed on effective treatments for IE caused by multidrug-resistant organisms in children.
