Multimodality Imaging of Mitral Perivalvular Abscess with Annular Fistula and Preserved Leaflet Function
Key result
Multimodality imaging successfully diagnoses a complex perivalvular mitral abscess and annular fistula in MRSA endocarditis.
- n=1
Why the study?
Periannular extension of infective endocarditis increases mortality, making cardiac imaging essential to accurately identify infection extent and guide surgical strategy.

Implication
Multimodal imaging may guide mitral abscess surgery; hypothesis-generating and requires prospective validation before practice change.
Key Points
- The aim is to highlight the role of multimodal imaging in diagnosing complex mitral valve infections.
- Described a case of a 62-year-old woman with mitral valve issues.
- Utilized 3D transesophageal echocardiography, computed tomography, and left ventriculography for diagnosis.
- Analyzed histopathological results to confirm absence of leaflet involvement.
- Identified a perivalvular mitral valve abscess with adjacent annular fistula.
- No evidence of mitral valve leaflet involvement was found on histopathology.
- This imaging approach aids in planning effective surgical interventions.

Intervention
Multimodality imaging (3-dimensional transesophageal echocardiography, computed tomography, and left ventriculography) and surgical debridement with mitral valve replacement.
Multimodality imaging, including 3D TEE and CT, is essential for accurately identifying the extent and complexity of periannular extension in infective endocarditis to guide surgical intervention.
Cite This Study
Yang et al. (2012) conducted a case report in Infective endocarditis with mitral perivalvular abscess (n=1). Multimodality imaging and surgical management was evaluated. Multimodality imaging successfully diagnosed a complex perivalvular mitral abscess with an annular fistula and preserved leaflet function in a 62-year-old woman with MRSA endocarditis.
