Summary
This study reports on two neonates with truncus arteriosus and type B interrupted aortic arch. Surgical repair involved a homograft for right ventricle to pulmonary artery connection and direct aortic anastomosis for arch continuity.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Neonatal Medicine
Background:
- Truncus arteriosus (TA) and interrupted aortic arch (IAA) are complex congenital heart defects.
- Type B IAA presents significant surgical challenges in neonates.
Observation:
- Two neonates diagnosed with both truncus arteriosus and type B interrupted aortic arch were identified.
- Detailed surgical procedures for these complex cases were documented.
Findings:
- A homograft was successfully utilized to establish continuity between the right ventricle and the pulmonary artery in both neonates.
- Direct anastomosis of the aortic arch to the descending aorta was performed to restore arch continuity.
Implications:
- This surgical approach demonstrates a viable strategy for managing combined truncus arteriosus and type B interrupted aortic arch.
- Successful outcomes in these complex cases may inform future treatment protocols for similar congenital heart defects.
