Stent implantation in right-sided patent ductus arteriosus to relieve severe cyanosis in adult patient with pulmonary atresia and ventricular septal defect.
Patients with unrepaired pulmonary atresia and ventricular septal defect may develop stenosis of collaterals or shunts to the pulmonary arteries leading to hypoperfusion of lungs and systemic hypoxemia. A 25-year-old female with pulmonary atresia and ventricular septal defect presented with progressively increasing cyanosis and exercise intolerance. A restrictive right-sided patent ductus arteriosus was identified as the main source of pulmonary blood flow. We report transcatheter implantation of a balloon-expandable stent across the stenosed duct to augment the pulmonary blood flow as a palliative management option. Patient had immediate improvement in arterial oxygen saturation from 66% to 85% with excellent clinical improvement and stable oxygen saturation on 8 months of follow-up.
