Why the study?
Fetal aortic valvuloplasty (FAV) aims to preserve biventricular circulation in critical fetal aortic stenosis, but it remains unclear how many patients achieve this postnatal outcome.
Does fetal aortic valvuloplasty improve the rate of biventricular circulation in fetuses with critical aortic stenosis?

Biventricular circulation achieved in ~46% of liveborn FAV cases; leaves open optimal selection criteria for prospective trials.
Does fetal aortic valvuloplasty improve the rate of biventricular circulation in fetuses with critical aortic stenosis?
Fetal aortic valvuloplasty achieves biventricular circulation in approximately 46% of liveborn patients with critical aortic stenosis, though the lack of randomized data limits definitive conclusions regarding its true benefit.
