Double orifice mitral valve associated with endocardial cushion defect
Japanese Circulation Journal
|May 1, 1986
Summary
Duplication of the mitral valve, a rare congenital heart defect, was observed in a child with an endocardial cushion defect. Echocardiography revealed two distinct mitral valve openings, aiding surgical repair.
Area of Science:
- Cardiology
- Congenital Heart Defects
- Pediatric Cardiac Surgery
Background:
- Mitral valve duplication is an exceptionally rare congenital cardiac anomaly.
- This case involves a pediatric patient with a partial endocardial cushion defect.
Observation:
- A 6-year-old girl presented with mitral valve duplication.
- The mitral orifice was divided by fibrous tissue, with each section possessing a subvalvular apparatus, except for a cleft region.
Findings:
- Two-dimensional echocardiography clearly showed two separate mitral valve orifices.
- Surgical repair of the cleft was successfully performed without complications.
Implications:
- This case highlights the diagnostic utility of echocardiography in identifying rare cardiac anomalies.
- Successful surgical management of mitral valve duplication associated with endocardial cushion defects is feasible.
