signals significance with p < .05.

Except for the occurrence of liver herniation, there is no difference in characteristics between patients with moderate and severe pulmonary hypertension (PH), but a striking difference in the outcome parameters extracorporal membrane oxygenation (ECMO)-rate and mortality. GA, gestational age; BW, birth weight; FETO, fetoscopic endoluminal tracheal occlusion; o/e LHR, observed/expected lung head ratio; TFLV, total fetal lung volume.
