[Pulmonary valvulotomy with the Nykanen radiofrequency guide in pulmonary atresia with intact interventricular septum].
We report 2 cases of pulmonary atresia with intact interventricular septum where perforation of the pulmonary valve was performed using a new Nykanen radiofrequency guide from Bayliss. The valvulotomy was successful in the two neonates, but one required secondary surgery to enlarge the pulmonary infundibulum. Moreover, in one of the two cases, this anomaly was associated with a right aortic arch without systemico-pulmonary vessels, which is a rare combination in this pathology. This technique is effective and safe, and represents a good alternative to open surgery in the forms with tripartite right ventricle and without coronaro-cardiac fistulae.
