Blalock-Taussig shunt for a neonatal case of Ebstein's anomaly with unobstructed right ventricular outflow tract.

A neonate with Ebstein's anomaly presented with severe cyanosis because of massive right-to-left shunt through an atrial septal defect and reduced blood flow through an unobstructed right ventricular outflow tract. This atypical patient underwent a right modified Blalock-Taussig shunt, which resolved the respiratory.
