Sildenafil use in a symptomatic neonate with severe Ebstein's anomaly of the tricuspid valve.

Ebstein's anomaly (EA) is associated with poor outcome in symptomatic neonates. Management typically includes prostaglandins or surgical creation of a Blalock-Taussig shunt. Right ventricular afterload reduction may help by improving the forward flow across the pulmonary valve. We report the successful use of oral sildenafil, a pulmonary vasodilator, in a neonate with severe EA.
