S. Milo et al., PUNCH PULMONARY VALVECTOMY - ANOTHER ALTERNATIVE TO TREAT CRITICAL PULMONARY STENOSIS, The Annals of thoracic surgery, 64(1), 1997, pp. 261-264
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 n
eonates, who were not suitable for any type of transcatheter procedure
, were treated. There were two late deaths, neither directly related t
o the operation; 4 patients are developing well. This approach using t
he valvectomy punch is a fast, safe, and effective procedure.
