Insights
Operative mortality for infants with interruption of the aortic arch remains high at 35%. Major coexisting heart defects and specific types of aortic arch interruption increase mortality risk.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Defects
- Aortic Arch Anomalies
Background:
- Interruption of the aortic arch is a severe congenital heart defect.
- Surgical repair is complex and associated with significant risks.
Purpose of the Study:
- To analyze the operative mortality rates for infants undergoing surgical repair of interrupted aortic arch.
- To identify risk factors associated with mortality in this patient population.
Main Methods:
- Retrospective review of 262 infants with interruption of the aortic arch.
- Data collected from 1982 to June 1993.
- Analysis of mortality and associated risk factors.
Main Results:
- Operative mortality remained constant at approximately 35% during the study period.
- Major coexistent cardiac malformations were identified as a significant risk factor.
- Type B interruption and staged repair strategies were also associated with increased mortality.
Conclusions:
- Surgical repair of interruption of the aortic arch continues to have a high mortality rate.
- Identifying and addressing risk factors such as complex anomalies and repair strategies is crucial for improving outcomes.
Abstract:
Operative mortality for 262 infants with interruption of the aortic arch repaired from 1982 to June 1993 has remained constant at about 35%. Major coexistent cardiac malformations, type B interruption, or staged repair are risk factors for mortality.
