Summary
A rare single coronary artery in a neonate with dextro-transposition of the great arteries was successfully treated with a novel coronary transfer technique. This innovative approach ensured a smooth coronary route post-surgery, offering hope for similar complex congenital heart cases.
Area of Science:
- Cardiology
- Congenital Heart Surgery
- Medical Imaging
Background:
- Dextro-transposition of the great arteries (dTGA) is a critical congenital heart defect.
- A single coronary artery originating from a single ostium is a rare anomaly, posing surgical challenges.
- Accurate anatomical assessment is crucial for planning surgical interventions in neonates.
Observation:
- A 6-day-old male neonate presented with dTGA and an intact ventricular septum.
- Computed tomography (CT) confirmed a rare single coronary artery with a single ostium arising from sinus 2 (2 R L Cx).
Findings:
- A novel coronary transfer technique utilizing a tubular pouch fashioned from native aortic tissue was successfully employed.
- Postoperative CT demonstrated a well-defined coronary artery pathway without evidence of stenosis.
Implications:
- This technique offers a viable solution for managing rare single coronary artery anomalies in neonates with complex heart conditions.
- Successful surgical correction can improve long-term outcomes for infants with dTGA and coronary anomalies.
- The described method advances surgical strategies in pediatric cardiac interventions.
