    Area of Science:

    • Cardiovascular Surgery
    • Pediatric Cardiology
    • Medical Devices

    Background:

    • Complex left ventricular outflow tract (LVOT) obstruction presents significant surgical challenges.
    • Traditional surgical approaches may be limited in specific pediatric and adult congenital heart disease cases.
    • Valved conduits offer a potential solution for severe LVOT obstruction.

    Purpose of the Study:

    • To assess the efficacy and safety of interposing valved conduits between the left ventricular apex and aorta.
    • To evaluate outcomes in patients with various complex LVOT obstructions, including tunnel subaortic stenosis and aortic hypoplasia.
    • To determine the long-term survival and complication rates associated with this surgical technique.

    Main Methods:

    • A retrospective analysis of 38 patients undergoing valved conduit implantation between the left ventricular apex and aorta over a 10-year period.

  • Indications included tunnel subaortic stenosis, aortic annular hypoplasia, supravalvular aortic hypoplasia, and severe ascending aorta calcification.
  • Patient outcomes, including operative mortality, survival rates, and major complications, were meticulously recorded.

    • Main Results:

    • Operative mortality was 11%.
    • Among survivors, 78% were alive at 5 years post-surgery.
    • 70% of survivors experienced no major complications, with better outcomes observed in adolescents and adults compared to young children.
    • Complications included valve calcification and conduit disruption at the ventricular apex insertion site.

    Conclusions:

    • Valved conduits between the left ventricular apex and aorta are a viable option for select patients with complex LVOT obstruction.
    • The procedure demonstrates acceptable long-term survival and complication profiles, particularly in older patient groups.
    • Despite potential complications, the technique remains valuable for specific challenging cases of LVOT obstruction.
