    Area of Science:

    • Pediatric Cardiac Surgery
    • Congenital Heart Disease
    • Cardiovascular Surgery

    Background:

    • Fallot's tetralogy is a complex congenital heart defect requiring surgical palliation.
    • Systemic-pulmonary shunts are used to improve pulmonary blood flow in affected patients.
    • Various shunt types exist, each with potential benefits and drawbacks.

    Purpose of the Study:

    • To evaluate the long-term efficacy and outcomes of different types of systemic-pulmonary shunts.
    • To compare the mortality rates and patency of Blalock-Taussig, Potts, and Waterston shunts.
    • To analyze surgical challenges and long-term results in patients with Fallot's tetralogy.

    Main Methods:

    • Retrospective analysis of 162 systemic-pulmonary shunts in 136 patients with Fallot's tetralogy.
    • Procedures included Blalock-Taussig, Potts, Waterston shunts, and shunts with interposed grafts.
    • Patients were followed for 1 to 23 years, with an average follow-up of 12.5 years.

    Main Results:

    • Total mortality ranged from 25% (Waterston) to 42% (Potts).
    • Immediate palliative effect was similar across shunt types in survivors.
    • Long-term patency favored Potts shunts over Blalock-Taussig shunts at over 20 years.

    Conclusions:

    • The choice of shunt type impacts long-term outcomes in Fallot's tetralogy palliation.
    • Potts shunts demonstrated better long-term patency compared to Blalock-Taussig shunts.
    • Further investigation into surgical techniques and long-term management is warranted.
