Pulmonary hypertension and persistent fetal circulation in the newborn.

Despite these infants' very significant medical instabilities, which require vigorous therapeutic intervention, we have seen a population of infants with little in the way of persistent residual problems. Although many of their pulmonary complications persist after hospital discharge, most resolve within the first year of life. In addition, there are few neurodevelopmental disabilities encountered in such a high-risk population of children.
