Summary
Truncal valve insufficiency complicates truncus arteriosus repair. Pericardial leaflet extensions successfully repaired quadricuspid truncal valves in two infants, offering a new surgical option.
Area of Science:
- Congenital heart disease
- Pediatric cardiac surgery
- Valvular heart disease
Background:
- Truncal valve insufficiency is a major risk factor for mortality after truncus arteriosus repair.
- Surgical repair of dysplastic and insufficient truncal valves presents a significant challenge.
Observation:
- Two infants with type 2 truncus arteriosus and severely dysplastic, insufficient quadricuspid truncal valves were identified.
- These infants underwent primary repair for their congenital heart condition.
Findings:
- A novel surgical technique utilizing pericardial leaflet extensions was employed to repair the truncal valves.
- The truncal valves in both infants were successfully repaired using this method during primary surgery.
Implications:
- Pericardial leaflet extension is a viable technique for managing truncal valve insufficiency in neonates undergoing primary truncus arteriosus repair.
- This approach may improve outcomes for infants with complex congenital heart defects involving the truncal valve.
