    The Taussig-Bing anomaly, when combined with mitral valve straddling, leads to poor surgical outcomes. A new surgical approach preserves mitral valve function and improves results for this complex congenital heart defect.

    Area of Science:

    • Congenital Heart Surgery
    • Pediatric Cardiology
    • Cardiac Anatomy

    Background:

    • The Taussig-Bing anomaly (Lev type) is a complex congenital heart defect.
    • Associated mitral valve straddling can complicate surgical outcomes.
    • Subpulmonic obstruction due to abnormal mitral leaflet attachment is a key concern.

    Purpose of the Study:

    • To investigate the impact of mitral valve straddling in Taussig-Bing anomaly.
    • To identify diagnostic clues for mitral valve straddling.
    • To propose and evaluate a novel surgical strategy.

    Main Methods:

    • Retrospective analysis of angiograms in four patients with fatal outcomes.
    • Angiographic diagnosis in a fifth patient.
    • Confirmation using cross-sectional echocardiography.

  • Development of a novel surgical technique.

    • Main Results:

    • Four of five patients with Taussig-Bing anomaly and mitral valve straddling died postoperatively due to unrecognized valve anomaly.
    • Diagnostic clues for mitral valve straddling were identified retrospectively.
    • A fifth patient was diagnosed preoperatively.
    • The proposed surgical approach successfully treated the fifth patient.

    Conclusions:

    • Mitral valve straddling is a critical, often unrecognized, factor in the poor prognosis of Taussig-Bing anomaly.
    • Early diagnosis and a tailored surgical approach are essential.
    • The proposed surgery preserves mitral valve function and bypasses the obstructive element, offering a viable treatment option.
