Restrictive Atrial Communication in Tricuspid Atresia With Minimal Duct-Dependent Pulmonary Circulation in a Newborn

Early identification of restrictive atrial communication and the determination of the effectiveness of pulmonary blood flow in tricuspid atresia are vital for preventing significant hemodynamic compromise. Ductal stenting with atrial septostomy is a viable, less invasive alternative to surgical shunt as first-stage palliation in newborns with duct-dependent tricuspid atresia.
