Summary
Fontan repair is a palliative surgery for complex heart disease. Thrombosis after this surgery can be treated with a redo Fontan operation, and prophylactic anticoagulation may reduce risks.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Fontan repair is a palliative surgical procedure for complex cyanotic congenital heart disease.
- Modified Fontan operations, specifically the right atrium-right ventricular connection with a conduit, can be complicated by thrombosis.
Observation:
- Two patients who previously underwent a Bjork modification Fontan operation developed thrombosis 6 and 9 years post-surgery.
- Thrombosis occurred in the right side of the heart in both cases.
Findings:
- Redo Fontan operations were successfully performed in both patients using a dacron tube graft.
- Post-operative anticoagulation was administered to both patients.
Implications:
- Redo Fontan operations are a viable treatment for post-Fontan thrombosis.
- Prophylactic anticoagulation in high-risk patients soon after Fontan repair may minimize the risk of thrombosis.
