A Genesis stent was implanted in two children, one with superior vena caval (SVC) stenosis and one with pulmonary artery branch stenosis. Case 1 was a 2-month-old baby with SVC stenosis following intracardiac repair for total anomalous pulmonary venous connection (TAPVC) and case 2 was a 2-year-old child with left lower pulmonary artery stenosis following one-stage unifocalization for dextrocardia, double outlet right ventricle, ventricular septal defect, pulmonary atresia and major aortopulmonary collateral arteries. Both procedures resulted in immediate clinical and hemodynamic improvement. The Genesis stent has a closed-cell design with sigma hinges interpositioned between each cell. With improved deliverability and expandability of the stent, we can easily deliver it through smaller sheaths, which will facilitate its use in infants and smaller children with vascular stenosis.
