Abstract

Background and objective: Chronic total occlusion (CTO) guidewire have been recently reported as an alternative to radiofrequency for perforating atretic pulmonary valve. Since procedure failures or perforation of the right ventricle still occurred with CTO, we tried to enhance the stability, steering, and pushability of the wire using a microcatheter in order to improve the safety and efficacy of the procedure.
Methods: We performed pulmonary valve perforation with CTO guidewire and microcatheter in five consecutive newborns with pulmonary atresia with intact ventricular septum (PA‐IVS) under fluoroscopic and echocardiographic control.
Results: The valve was easily perforated at the first attempt for all patients. After perforation, the microcatheter positioned in the main pulmonary artery allowed the exchange of the CTO guidewire for a more flexible wire, avoiding lesion and facilitating manipulation in the distal pulmonary branch arteries. The pulmonary valve was then dilated with balloons of increasing size as usually performed. We did not experience any procedural or early complications. Blalock‐Taussig shunt was performed in 2 children because of a persistent cyanosis, 4 and 10 days after perforation.
Conclusion: The combined use of a CTO guide and a microcatheter appears to be a safe and reliable technique for perforating the pulmonary valve of newborns with PA‐IVS. Further procedures with this approach are needed to confirm this first experience.
