Objective:

To develop a dynamic simulation platform for evaluating surgical repairs of the left atrioventricular valve (LAVV) in patients with atrioventricular canal (AVC) defects.

Approach:
    Key Findings:
    • 5–20% of LAVV repairs require reintervention, with significant risks associated with repeat surgeries.
    • Key predictors of reintervention include age at repair, AVC anatomy, left ventricular dysfunction, and multiple regurgitant jets.
    • Dynamic simulations can bridge the gap between static modeling and real-world surgical conditions, potentially improving surgical outcomes.
    Interpretation:

    Remove unsupported conclusions and editorial interpretations.

    Limitations:
    • The study is based on a limited number of patient cases.
    • Existing simulators have primarily focused on adult mitral valve disease, lacking adaptations for pediatric congenital valves.
    Conclusion:

    Remove unsupported claims and editorial interpretations.
