A focus on the remarkable add-on value of chronic total occlusion guidewires in the armamentarium of atretic pulmonary valve perforation

Raymond N. HADDAD, Zakhia SALIBA

Continuous advances in the technology of Chronic Total Occlusion (CTO) hardware have led to the development of a wide range of specialty guidewires with increased maneuverability, tip support, torque force, and penetrating power. We and other congenital interventionists described the safe, efficient, and effective use of CTO wires in percutaneous Pulmonary Valve (PV) mechanical perforations. Consecutive reports highlighted the importance of these CTO wires in the armamentarium and discussed their high potential in substituting other methods of endovascular perforation. Herein, we will review the reported experiences with CTO wires and discuss the procedural advantages and technical aspects of these wires in transcatheter treatment of Pulmonary Atresia with Intact Ventricular Septum (PA/IVS).
