    Summary

    The Fontan operation, particularly with a valved conduit, offers a good palliative treatment for tricuspid atresia and selected cases of single ventricle, showing improved hemodynamics and patient outcomes.

    ESMO open·2022

    Area of Science:

    • Cardiovascular Surgery
    • Pediatric Cardiology
    • Congenital Heart Disease

    Background:

    • Tricuspid atresia and single ventricle represent complex congenital heart defects requiring surgical palliation.
    • The Fontan operation has evolved as a primary surgical approach for these conditions.

    Purpose of the Study:

    • To evaluate the efficacy and outcomes of the Fontan operation performed up to December 1980.
    • To compare different surgical techniques, specifically valved versus non-valved conduits, and their hemodynamic impact.

    Main Methods:

    • Retrospective analysis of 21 Fontan operations performed between January 1970 and December 1980.
    • Categorization of patients into tricuspid atresia (8) and functional single ventricle (13) groups.
    • Comparison of outcomes based on the type of atriopulmonary connection (valved conduit vs. non-valved tunnel) and prosthesis size.

    Main Results:

    • Valved atriopulmonary conduits yielded more satisfactory immediate postoperative hemodynamic results compared to non-valved connections.
    • Larger prostheses correlated with better immediate hemodynamic outcomes.
    • Patients with single ventricle required careful preoperative selection, particularly regarding pulmonary vascular resistance.
    • Two single ventricle patients successfully underwent reoperation for persistent shunting.
    • 13 patients followed for at least one year demonstrated significant clinical improvement.

    Conclusions:

    • The Fontan operation with a valved conduit is an effective palliative treatment for tricuspid atresia.
    • Modified Fontan procedures can yield good results in selected single ventricle patients.
    • Careful patient selection and appropriate prosthesis choice are crucial for optimal outcomes.
    • No late complications related to valved prostheses were observed in this cohort.
