    Postoperative pulmonary vein stenosis (PVS) occurred in 18% of pediatric heart transplant recipients, with a median diagnosis time of 84 days.

  • 2

    Congenital heart disease (CHD) was identified as the only significant risk factor for PVS in multivariate analysis, with an odds ratio of 11.25.

  • 3

    Donor-recipient size mismatch parameters were greater among patients with PVS, but this association requires validation in larger studies.

  • 4

    PVS did not significantly affect overall survival probability in pediatric heart transplant recipients.

  • 5

    The study emphasizes the need for ongoing surveillance and preventive strategies for high-risk groups in pediatric heart transplantation.
