A pediatric cardiologist and director of the pulmonary hypertension program at The Children’s Hospital of Philadelphia offers his insight on pulmonary hypertension associated with pediatric neonatal chronic lung disease.

At his facility, neonatal chronic lung disease is the cause of pulmonary hypertension in 300 of 670 active patients.

“The problem is that this is not pulmonary hypertension the way that pediatric cardiologists have been treating pulmonary hypertension for the past 15 years. This is pulmonary hypertension that is associated with lung hypoplasia, developmental delays, and significant loss of capillary bed as a result of diseases that are associated with chronic lung disease,” he says.
