Summary
Primary repair of interrupted aortic arch (IAA) with ventricular septal defect (VSD) in infants shows improved outcomes. Awareness of potential complications like subaortic stenosis is crucial for successful management.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Defects
Background:
- Interrupted aortic arch (IAA) with ventricular septal defect (VSD) is a critical congenital heart condition.
- Surgical repair strategies have evolved to improve outcomes in affected neonates.
Purpose of the Study:
- To evaluate the outcomes of primary versus staged surgical repair for IAA with VSD.
- To identify associated conditions and long-term sequelae following repair.
Main Methods:
- Retrospective analysis of 24 infants undergoing IAA with VSD repair between 1975 and 1982.
- Comparison of outcomes between primary repair and staged/palliative approaches.
- Hemodynamic evaluation via catheterization in survivors 1-3 years post-repair.
Main Results:
- Overall mortality rates were 27% early and 13% late for staged repair, and 23% early for primary repair.
- No significant residual VSD or aortic pressure gradients were noted in survivors.
- Six of 14 survivors developed subaortic stenosis, requiring further intervention.
Conclusions:
- Primary repair of IAA with VSD is associated with favorable outcomes and is the preferred approach.
- Subaortic stenosis and hypocalcemia are important associated conditions to monitor post-repair.
- Continuous improvement in surgical results for neonates with IAA is evident.
