    This study compared clinical and morphological outcomes of autologous pericardial patches and pulmonary artery patches in infants undergoing aortic arch reconstruction.

  • 2

    Cardiopulmonary bypass and cross-clamp times were significantly longer for pulmonary artery patches, but early mortality rates were similar between both patch types.

  • 3

    An elevated pre-discharge systolic peak velocity greater than 2.48 m/s was a significant predictor of recoarctation in the studied cohort.

  • 4

    While pulmonary artery patches initially produced a larger arch diameter, both patch types exhibited similar mid-term growth trajectories.

  • 5

    The study concluded that achieving optimal initial geometric relief is more critical than patch selection for preventing late recoarctation.
