For neonates with severe valvar stenosis, or valvar pulmonary atresia with an imperforate pulmonary valve, we present a simple but effective closed procedure using a specially designed valvectomy punch. Seven neonates, who were not suitable for any type of transcatheter procedure, were treated. There were two late deaths, neither directly related to the operation; 4 patients are developing well. This approach using the valvectomy punch is a fast, safe, and effective procedure.
