Fetal Risk Stratification and Outcomes in Children with Prenatally Diagnosed Lung Malformations: Results from a Multi-Institutional Research Collaborative

Multi-institutional study of 344 prenatally diagnosed congenital lung malformations identified CVR thresholds that predict outcomes: initial CVR ≤1.4 indicates low hydrops risk, while maximum CVR <0.9 correlates with asymptomatic disease at birth. These findings enable standardized prenatal counseling and delivery planning for fetal lung malformations.
