Data from pre-procedural imaging, intraoperative parameters, and post-procedural outcomes were analysed. The primary endpoints were improvement in systemic oxygen saturation and pulmonary artery growth. Secondary endpoints included complication rates, ICU stay duration, and factors associated with procedural failure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S104795112511055X_as3\">\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The median age at intervention was 11 months. All patients presented with cyanosis, and 80% had documented cyanotic spells. The right internal jugular vein was used for vascular access in 75% of cases. A significant improvement was observed in systemic oxygen saturation (from 67.8 to 87.1%,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001), along with an increase in pulmonary artery Z-scores. Complications included pulmonary oedema (47%), stent migration (7.2%), and new-onset tricuspid regurgitation (26.9%). The procedure had a success rate of 83.6%. Although no significant predictors of failure or prolonged ICU stay were identified, furosemide use was associated with a longer recovery time.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S104795112511055X_as4\">\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Right ventricular outflow tract stenting serves as a safe, effective, and reproducible palliative option in selected neonates with Fallot physiology.
