Novel catheter positioning technique for atretic pulmonary valve perforation.

Percutaneous pulmonary valve perforation in selected neonates with pulmonary valve atresia and intact ventricular septum has been well established as a therapeutic option. Pulmonary valve perforation is associated with significant risks including perforation of the right ventricle. Optimal catheter positioning is crucial to the success of the procedure. This report describes a novel technique for accurate positioning of a guiding catheter during perforation of an atretic pulmonary valve. 2008 Wiley-Liss, Inc.
