Stenting stenosed aortopulmonary collateral arteries in pulmonary atresia with ventricular septal defect

We present two cases of pulmonary atresia with ventricular septal defect who were not suitable for corrective surgery due to absent or hypoplastic native pulmonary arteries and were quite symptomatic following shunt surgery. We dilated and stented stenosed aortopulmonary collaterals as palliative procedure with improvement in oxygen saturation, and significant symptomatic relief.
