Summary
This report details a rare mitral valve aneurysm in a 67-year-old woman, successfully treated with mitral valve replacement. Infective endocarditis was the likely cause of this serious cardiac condition.
Area of Science:
- Cardiology
- Cardiac Surgery
- Pathology
Background:
- Infective endocarditis can lead to rare complications such as mitral valve aneurysms.
- Mitral valve aneurysms, though uncommon, can result from various conditions including congenital anomalies and inflammatory syndromes.
Observation:
- A 67-year-old woman presented with mitral and aortic valve regurgitation secondary to infective endocarditis.
- Preoperative echocardiography identified an aneurysmal change and prolapse of the anterior mitral leaflet.
- Left ventriculography confirmed severe mitral regurgitation (Sellers IV).
Findings:
- Histopathological examination revealed a perforated valvular aneurysm (21 x 15 x 11 mm) with an inflammatory cleft on the anterior mitral leaflet.
- The patient successfully underwent mitral valve replacement with a 27 mm Carbo Medicus prosthesis.
Implications:
- Mitral valve replacement is the preferred surgical option for large, perforated, or severely inflamed mitral valve aneurysms.
- This case underscores the importance of recognizing and managing rare cardiac pathologies arising from infective endocarditis.
- Prompt surgical intervention is crucial for favorable outcomes in patients with significant mitral valve dysfunction due to aneurysm.
