Summary
A rare congenital heart defect, a forme fruste of hammock valve, affects only the posterior mitral leaflet. This previously unreported lesion causes severe mitral regurgitation in adults, requiring surgical repair.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Hammock valve is a rare congenital anomaly of the mitral valve.
- This condition typically involves both mitral leaflets.
- A forme fruste variant affecting only the posterior leaflet is described here.
Observation:
- Three adult patients presented with severe mitral regurgitation.
- Diagnosis of posterior leaflet fibrosis was suspected preoperatively.
- Intraoperative findings revealed accessory papillary muscles attached to the posterior mitral leaflet.
Findings:
- Accessory papillary muscles arranged in a palisade formation restricted posterior leaflet motion during systole.
- This previously unreported congenital lesion manifests in adulthood.
- Surgical repair involved dividing accessory papillary muscles, patch augmentation, and ring annuloplasty.
Implications:
- This study identifies a novel congenital heart defect, a forme fruste of hammock valve.
- Early recognition and surgical intervention are crucial for managing this condition.
- Understanding this variant expands knowledge of mitral valve anomalies and their surgical management.
