Endocarditis with acute mitral regurgitation caused by Fusobacterium necrophorum
Pediatric Cardiology
|October 1, 1992
Abstract:
Infective endocarditis is uncommon in young children, especially in the absence of structural heart disease. We report the case of a 2-year-old boy who presented with acute rupture of the mitral valve chordae 6 weeks after an episode of Fusobacterium necrophorum septicemia. His heart had been structurally normal before. Mitral valve replacement was successfully performed. This is the first recorded case of endocarditis in a child caused by necrobacillosis.
Insights
Infective endocarditis is rare in children. A 2-year-old experienced mitral valve chordae rupture after Fusobacterium necrophorum septicemia, marking the first pediatric necrobacillosis endocarditis case.
Area of Science:
- Pediatric Cardiology
- Infectious Diseases
- Cardiovascular Surgery
Background:
- Infective endocarditis (IE) is uncommon in young children, particularly those without congenital heart defects.
- Fusobacterium necrophorum septicemia can lead to severe complications, though IE is a rare manifestation.
- This case highlights a previously undocumented association between F. necrophorum and IE in pediatric patients.
Observation:
- A 2-year-old boy with a structurally normal heart developed acute mitral valve chordae rupture.
- The rupture occurred 6 weeks following an episode of Fusobacterium necrophorum septicemia.
- The patient presented with symptoms indicative of severe mitral regurgitation.
Findings:
- The patient was diagnosed with infective endocarditis caused by Fusobacterium necrophorum.
- This represents the first documented case of endocarditis in a child attributed to necrobacillosis.
- Successful mitral valve replacement was performed, resolving the acute cardiac complication.
Implications:
- This case expands the known spectrum of complications associated with Fusobacterium necrophorum infections in children.
- It underscores the importance of considering IE in pediatric patients with unexplained septicemia and cardiac symptoms, even without pre-existing heart conditions.
- Early diagnosis and surgical intervention are crucial for managing severe valvular damage in pediatric infective endocarditis.
