Infective endocarditis in children

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.
