Percutaneous pulmonary valvulotomy using radiofrequency in pulmonary atresia with an intact interventricular septum

Early pulmonary valvulotomy in patients with pulmonary atresia and intact i nterventricular septum allows the development and growth of the right ventr icle and two-ventricle circulation. Percutaneous valvulotomy today is a val id alternative procedure to surgical valvulotomy. With the use of the radio frequency 5F currently available for the treatment of arrythmias atretic pu lmonry valve perforation and consecutive balloon dilation may be safely and effectively performed. We describe a case of perforation of a pulmonary va lve by radiofrequency in a 15-day-old neonate with pulmonary valve atresia and intact ventricular septum.
