Transcatheter Radiofrequency Perforation in Pulmonary Valve Atresia with Intact Ventricular Septum in a Newborn

In a 4-day-old newbom with valvular pulmonary atresia with intact ventricular septum an open right ventricular outflow tract was created by means of interventional cardiological methods. Following an inadvertant perforation without sequelae or elinical symptoms, radiofrequency perforation and supsequent balloon dilation were performed. Because of severe right ventricular hypoplasia and residual pulmonary stenosis he needed subsequent systemic-pulmonary arterial shunt and reballooning of the pulmonary valve, respectively. The baby was discharged uneventfully after one month.
