Abstract:
We herein presented a 17-year-old female with history of mild mitral valve prolapse who was admitted for methicillin-sensitive Staphylococcus aureus endocarditis and diagnosed with mitral annular disjunction and perforated posterior mitral valve leaflet on two-dimensional and three-dimensional echocardiography (P1-P2). A perforation in the posterior leaflet was confirmed and repaired during surgical intervention. This is a rare presentation of leaflet perforation in the area of mitral annular disjunction.
Insights
A rare case of methicillin-sensitive Staphylococcus aureus endocarditis in a young female revealed mitral annular disjunction and a perforated mitral valve leaflet. Surgical repair was successful, highlighting a unique presentation of this cardiac condition.
Area of Science:
- Cardiology
- Cardiac Surgery
- Infectious Diseases
Background:
- Mitral valve prolapse and Staphylococcus aureus endocarditis are known cardiac conditions.
- Mitral annular disjunction is a rare echocardiographic finding, often associated with mitral valve pathology.
Observation:
- A 17-year-old female presented with methicillin-sensitive Staphylococcus aureus endocarditis.
- Echocardiography revealed mitral annular disjunction and a perforated posterior mitral valve leaflet (P1-P2 segment).
Findings:
- Surgical intervention confirmed the posterior mitral leaflet perforation.
- The perforated leaflet was successfully repaired during surgery.
Implications:
- This case highlights a rare association between mitral annular disjunction and infectious endocarditis with leaflet perforation.
- Early diagnosis and surgical management are crucial for favorable outcomes in such rare cardiac presentations.
