Key result
New 2F Coe RF catheter successfully perforates an atretic pulmonary valve membrane in a newborn.
Why the study?
Transcatheter therapy options for neonates with pulmonary atresia and intact ventricular septum require advancement to improve procedural success and safety.
Does the new 2 French Coe radiofrequency end hole catheter allow successful transcatheter perforation of the atretic pulmonary valve membrane in a newborn with pulmonary atresia and intact ventricular septum?

Does the new 2 French Coe radiofrequency end hole catheter allow successful transcatheter perforation of the atretic pulmonary valve membrane in a newborn with pulmonary atresia and intact ventricular septum?
The new 2 French Coe radiofrequency end hole catheter offers a successful transcatheter approach for perforating the atretic pulmonary valve membrane in neonates with pulmonary atresia and intact ventricular septum.
Successful perforation in one neonate; hypothesis-generating and requires prospective studies before clinical adoption.
The new 2 French Coe radiofrequency (RF) end hole catheter was first used to successfully perforate the atretic pulmonary valve membrane using an antegrade approach in a newborn with intact ventricular septum (IVS). Nine watts of energy for 8 sec was required with simultaneous delivery of a 0.014 in. coronary guidewire coaxially through the end hole RF catheter for balloon valvuloplasty. This new ringed-tip end hole RF catheter offers considerable advantages to the pediatric interventionalist in the transcatheter therapy in neonates with pulmonary atresia (PA) and IVS.

Cheatham et al. (1998) conducted a case report in Pulmonary atresia with intact ventricular septum (n=1). 2 French Coe radiofrequency end hole catheter was evaluated on Perforation of the atretic pulmonary valve membrane. The new 2 French Coe radiofrequency end hole catheter successfully perforated the atretic pulmonary valve membrane in a newborn using 9 watts of energy for 8 seconds.
