Primary restrictive foramen ovale.
A newborn infant with primary restrictive foramen ovale, tubular hypoplasia of the aortic arch, and some other developmental defects is described. This combination resulted in fetal hydrops, as was shown by ultrasonography. The child died 24 h after birth due to low output syndrome and extensive bronchopneumonia. The pathogenesis of this clinical entity is discussed.
