Summary
The Fontan operation is an accepted surgical method for complex congenital heart defects, offering an 83.8% ten-year survival rate. Early mortality is lower in tricuspid atresia patients, while complex malformations and single ventricles carry higher risks.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Congenital Heart Disease
Background:
- The Fontan operation is a palliative procedure for complex cyanotic heart disease.
- Patient selection and surgical modifications influence outcomes.
Purpose of the Study:
- To evaluate the outcomes of the Fontan operation in a diverse patient cohort.
- To identify risk factors for mortality and complications.
Main Methods:
- Retrospective review of 152 patients undergoing Fontan operation between 1980 and 1990.
- Analysis of patient groups including tricuspid atresia, single ventricle, and complex malformations.
- Comparison of outcomes based on prior palliative procedures and surgical modifications.
Main Results:
- Overall ten-year survival rate was 83.8%.
- Tricuspid atresia patients had significantly lower early mortality (8.5%) compared to complex malformations (28.2%) and single ventricle (19.4%).
- Fontan-Bjoerk modification was associated with reduced pleural effusion (p < 0.05).
Conclusions:
- Modified Fontan procedures offer an accepted surgical option for complex cardiac malformations.
- Patient-specific factors, particularly the underlying cardiac defect, significantly impact survival.
- Surgical modifications like the Fontan-Bjoerk procedure can improve postoperative outcomes.
