title: Transcatheter retrograde radio-frequency perforation of the pulmonic valve in pulmonary atresia with intact ventricular septum, using a 2 French catheter.
abstract: A neonate with pulmonary atresia with intact ventricular septum (PA/IVS) underwent successful retrograde transcatheter perforation of the pulmonary valve, using a 2 Fr radio-frequency catheter with subsequent anterograde balloon dilation of the valve. Due to persistent hypoxemia, the neonate underwent placement of a 4-mm modified Blalock-Taussig shunt. Transcatheter retrograde transductal perforation of the pulmonic valve in PA/IVS is feasible and may be a potential alternative to anterograde perforation.
