Pulmonary hypertension in congenital diaphragmatic hernia: Antenatal prediction and impact on neonatal mortality

To determine the prevalence of pulmonary hypertension (PAH) in the left‐sided congenital diaphragmatic hernia (CDH), how we could predict it, and how PAH contributed to the model for mortality prediction. Of the 197 neonates, 56 (28.4%) died. At d1, 67.5% (133/197) had PAH and 61.9% (101/163) by d7. Antenatal prediction of PAH was only moderate. The postnatal occurrence of PAH further increases the risk of death. Whereas this may be used to counsel parents in the postnatal period, our study demonstrates there is a need to find more accurate antenatal predictors for PAH.
