After echocardiography confirmation of PDA dependent pulmonary circulation in cyanotic neonates, catheter-guided PDA stent implantation will be done. Under general Anasthesia and after discontinuation of prostaglandin 4-6 hours before procedure, obtain vascular access and unfractionated heparin is given, then duct is accessed via a cut pig-tail or Judkins right \[JR\] catheter, and is crossed by PTCA wire to be carefully placed in the left or right branch pulmonary arteries, choose proper stent diameter and length, place the stent and confirm it's position, NICU admission for the neonate with heparin infusion for 24-48 hrs and acetylsalicylic acid is given then follow up the patient by pulse oximeter and echocardiography

PDA stent is the primary treatment for patients with duct-dependent pulmonary circulation. It serves as a temporary bridge for later surgical repair by keeping the duct patent to improve oxygen saturation

RECRUITINGChange in Oxygen saturation
Using pulse oximeter to assess oxygen saturation
Time frame: Change in oxygen saturation within 24 hours
Evaluation of duct patency
Using echocardiography assess flow through the duct
Time frame: 1 month
