Pulmonary Hypertension in Patients with Congenital Diaphragmatic Hernia: Does Lung Size Matter?

Retrospective study of 62 infants with isolated CDH examining correlation between prenatal lung size measurements (o:eLHR and PPLV) and postnatal pulmonary hypertension severity. Both metrics significantly predicted PHTN grade and need for therapies like iNO and epoprostenol, with stronger associations in ECMO patients, suggesting prenatal imaging can guide postnatal management.
