Summary
Arterial switch operations can lead to neoaortic dilation, necessitating further surgery. This case highlights a successful David procedure for aortic root replacement in a young adult with complex anatomy post-ASO.
Area of Science:
- Cardiovascular Surgery
- Congenital Heart Disease
- Aortic Surgery
Background:
- Arterial switch operation (ASO) is a critical neonatal procedure for transposition of the great arteries.
- Neoaortic dilation is a potential long-term complication requiring reintervention.
- The David procedure offers an alternative for aortic root repair.
Observation:
- A 25-year-old female presented with significant neoaortic dilation.
- The patient had a history of ASO with unusual anterior positioning of the pulmonary artery and coronary arteries.
- This unique anatomy presented surgical challenges for aortic root replacement.
Findings:
- A successful David procedure was performed to address the neoaortic dilation.
- The surgical approach was adapted to manage the anteriorly positioned great vessels and coronary origins.
- This case demonstrates the feasibility of the David procedure in complex post-ASO anatomy.
Implications:
- The David procedure is a viable option for managing neoaortic dilation in adults with complex congenital heart defects.
- Surgical planning must account for unique anatomical variations resulting from prior ASO.
- This approach may improve long-term outcomes for patients with transposition of the great arteries.
