Use of a cerebral angiographic catheter facilitates crossing the pulmonary valve in neonates with critical or severe pulmonary valve stenosis.
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.
