Overview

A retrospective study finds safe surgical repair outcomes after RVOT stenting in neonates with TOF, suggesting early intervention is beneficial.

Key Points

  • To evaluate the outcomes of surgical repair following right ventricular outflow tract (RVOT) stenting in patients with tetralogy of Fallot (TOF).
  • Retrospective analysis of 11 patients who underwent RVOT stenting followed by surgical repair.
  • Data collected included demographics, intraoperative findings, pulmonary artery growth, and postoperative outcomes.
  • Assessment of pulmonary artery growth using z-scores pre- and post-stenting.
  • Analysis of the correlation between time from stenting to surgery and operative duration.
  • 91% of patients had complete stent excision during surgery.
  • 90.9% required transannular patch repair.
  • Significant improvement in prestent pulmonary artery z-scores was observed by surgery.
  • Maximum pulmonary artery growth noted within 5 months post-stenting.
  • No in-hospital or 30-day mortality was reported.
