Summary
This study reports a successful arterial switch operation for a neonate with simple transposition of the great arteries. The patient achieved the longest survival at this hospital following the procedure.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease
- Neonatal Cardiology
Background:
- The arterial switch operation (ASO) is a complex surgical procedure for treating transposition of the great arteries (TGA).
- Historically, ASO at this institution was reserved for hyperdynamic TGA beyond the neonatal period.
- This case explores ASO in a neonate with simple TGA, challenging previous institutional practice.
Observation:
- A 20-day-old female infant presented with simple TGA.
- The patient underwent an arterial switch operation on March 3, 1992.
- A unique surgical technique involving an autologous aortic flap was employed for coronary artery augmentation.
Findings:
- The infant's coronary artery pattern was identified as Shaher's type 4.
- The surgical augmentation technique utilized an autologous aortic flap to enhance the left circumflex coronary artery.
- The patient survived the procedure and has shown positive recovery for three years post-operation.
Implications:
- This case demonstrates the feasibility and long-term success of ASO in neonates with simple TGA, even with complex coronary anatomy.
- The use of an autologous aortic flap for coronary augmentation represents a potential refinement in ASO techniques.
- This outcome establishes a new benchmark for the longest survival following neonatal ASO at the hospital.
