Survival after prolonged persistent pulmonary hypertension.
We report an infant with prolonged persistent pulmonary hypertension (PPH) who failed to respond to various mechanical and pharmacological therapies but who showed spontaneous improvement at 13 days of age. We therefore stress that assisted ventilation should be continued in PPH without major structural cardiac or pulmonary abnormality or ongoing iatrogenic complications, as recovery may occur at any time.
