Overview

Technical success in two cases did not prevent death from LV dysfunction; leaves open whether earlier intervention improves survival in fetal critical aortic stenosis.

Intrauterine balloon dilatation of the aortic valve is technically feasible in fetuses with critical aortic stenosis, but survival remains poor due to irreversible left ventricular damage.
