Pulmonary Atresia and Ventricular Septal Defect Without Major Aortopulmonary Collateral Arteries: Diagnostic Evaluation and the Role of Ductal Stenting.

ABSTRACT

Patients with pulmonary atresia (PA) and a ventricular septal defect (VSD), similar to those with tetralogy of Fallot and PA without major aortopulmonary collateral arteries, lack antegrade pulmonary blood flow, and thus require a neonatal intervention for stabilization or augmentation of pulmonary blood flow. The role of ductal stenting in the management of these patients, and the current literature supporting it, will be reviewed.
