title: Use of a cerebral angiographic catheter facilitates crossing the pulmonary valve in neonates with critical or severe pulmonary valve stenosis.
abstract: The inability to cross the pulmonary valve in neonates with severe pulmonary stenosis remains a primary reason for procedural failure. We describe the use of a standard pediatric cerebral angiographic catheter that enables crossing the pulmonary valve in these neonates with relative ease and rapidity.
