Why the study?
To document semilunar valve growth in fetal transposition of the great arteries and evaluate the relationship between prenatal pulmonary valve annulus dimensions and postoperative neo-aortic root dilatation.
Does prenatal pulmonary valve annulus dimension correlate with postoperative neo-aortic root dilatation in fetuses with transposition of the great arteries undergoing arterial switch operation?
Population
137 TGA fetuses suitable for ASO
Comparison
TGA semilunar valve annulus trends vs normal control values
Design
Retrospective multicenter observational study

Observational TGA data link prenatal PV size to post-ASO NAoR dilatation; leaves open whether fetal monitoring alters reintervention risk or counseling.
Does prenatal pulmonary valve annulus dimension correlate with postoperative neo-aortic root dilatation in fetuses with transposition of the great arteries undergoing arterial switch operation?
Fetal TGA semilunar valve annuli are larger than normal, and prenatal pulmonary valve dimensions correlate significantly with postoperative neo-aortic root dilatation, suggesting fetal anatomy influences late reintervention risk.
