title: [Functional atresia of the pulmonary valve].
abstract: Three newborn children with cyanosis due to Ebstein's anomaly of tricuspid valve with an important hemodynamic repercussion presented features of imperforation of pulmonary valve. On the follow-up, clinical and laboratory findings verified that pulmonary atresia was functional resulting from a combination of low right ventricular pressure and high pulmonary vascular resistance.
