Recurrent endocarditis on restrictive perimembranous septal defect causing aortic insufficiency

Area of Science:

• Pediatric Cardiology
• Infectious Diseases
• Cardiac Surgery

Background:

• Infective endocarditis (IE) is rare in children but carries a high event rate.
• Ventricular septal defect (VSD) is a primary predisposing condition for pediatric IE.
• Long-term IE follow-up is challenging due to relapse and reintervention risks.

Observation:

• A child with a restrictive perimembranous VSD experienced recurrent IE.
• Severe aortic regurgitation developed after surgical closure of the VSD.
• The patient required reoperation due to IE complications.

Findings:

• Recurrent IE on a repaired VSD can lead to significant valve damage.
• Post-surgical aortic regurgitation is a potential complication of IE in VSD patients.
• Surgical intervention may be necessary for managing IE-induced aortic valve lesions.

Implications:

• This case underscores the importance of vigilant long-term monitoring for pediatric IE patients, especially those with congenital heart defects.
• Early recognition and management of complications like aortic regurgitation are crucial for favorable outcomes.
• Further research into preventative strategies and optimal management protocols for recurrent IE in children is warranted.
