|December 1, 1983
Summary
This study compared two surgical approaches for infants with interruption of the aortic arch, ventricular septal defect, and patent ductus arteriosus. Primary total correction demonstrated improved outcomes compared to initial palliative procedures.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Defects
- Cardiovascular Surgery
Background:
- Infants with interruption of the aortic arch (IAA), ventricular septal defect (VSD), and patent ductus arteriosus (PDA) present complex surgical challenges.
- Early surgical management strategies evolved over time to improve patient outcomes.
Purpose of the Study:
- To compare the outcomes of palliative surgical procedures versus primary total correction in infants with IAA, VSD, and PDA.
- To evaluate the effectiveness of deep hypothermia and circulatory arrest in primary total correction.
Main Methods:
- Retrospective analysis of 14 infants operated between 1974 and 1983 for IAA, VSD, and PDA.
- Initial group underwent palliative surgery: aortic arch reconstruction, PDA closure, and pulmonary artery banding (PBA).
- Subsequent group underwent primary total correction using deep hypothermia and circulatory arrest.
Main Results:
- Five patients initially received palliative surgery, with three deaths (60% mortality). Survivors required subsequent VSD closure.
- Nine patients underwent primary total correction, with two deaths (22% mortality).
Conclusions:
- Primary total correction, especially since 1979, is associated with significantly lower mortality rates for IAA, VSD, and PDA compared to palliative approaches.
- The use of deep hypothermia and circulatory arrest in primary total correction has improved surgical results for this complex congenital heart defect.
