Abstract

This is a bit more difficult than simple valvar PS as previously discussed. Patients with critical valvar PS are cyanotic at birth and require PGE maintenance of pulmonary blood flow. Right-sided hypoplasia is rarely a limiting factor in newborns with critical PS. The appearance of a dysplastic valve, by angiography or echocardiography, has not been found to predict dilation outcome in neonates (1).
