Successful transcatheter perforation of the atretic pulmonary valve membrane in a newborn using the new Coe radiofrequency end hole catheter.
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.
