Summary
Unusual venous anatomy in two patients allowed right-to-left shunting after Fontan repair. This finding highlights potential complications in complex congenital heart disease management.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- The Fontan procedure is a palliative surgery for single-ventricle physiology.
- Post-Fontan complications can arise from altered hemodynamics and venous pathways.
Observation:
- Two pediatric patients exhibited atypical venous anatomy post-Fontan repair.
- This anatomy facilitated an unusual right-to-left shunt at the atrial level.
Findings:
- The identified venous variations enabled direct right-to-left shunting, bypassing normal pulmonary circulation.
- This anatomical anomaly can lead to cyanosis and other Fontan-associated risks.
Implications:
- Understanding rare venous variations is crucial for managing Fontan patients.
- This case series emphasizes the need for individualized pre-operative and post-operative assessments.
