The Journal of Thoracic and Cardiovascular Surgery
|April 1, 1976
Summary
This report details a pediatric case of supravalvular stenotic mitral ring, a rare condition causing severe mitral stenosis. Surgical resection of the ring successfully treated the condition, highlighting diagnostic and management insights.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Supravalvular stenotic mitral ring is a rare congenital anomaly.
- It can mimic severe mitral stenosis, posing diagnostic challenges in pediatric patients.
- Understanding its unique presentation is crucial for appropriate management.
Observation:
- A case of supravalvular stenotic mitral ring in a child is presented.
- The lesion mimicked severe mitral stenosis.
- No other mitral valve or left ventricular outflow tract anomalies were identified.
Findings:
- Surgical resection of the supravalvular ring provided successful management.
- Angiographic morphology appears to be the most reliable diagnostic criterion.
- Associated ventricular septal defects or Shone's complex findings suggest this specific type of mitral stenosis.
Implications:
- This case underscores the importance of considering supravalvular stenotic mitral ring in pediatric mitral stenosis.
- Accurate diagnosis through specific angiographic findings is key.
- Timely surgical intervention can lead to favorable outcomes.
