Objective: Fetal aortic valvuloplasty (FAV) may avoid progression of critical aortic stenosis (CAS) to hypoplastic left ventricle, improving the options for biventricular circulation (BVC). We describe the results of FAV in 2 referral centers in Spain.Methods: We analyzed all FAVs performed in the period 2007-2015. The selection of candidates, the technique, and postnatal management were made following an agreed protocol. A descriptive analysis of survival, type of circulation after birth, and complications was made, considering all deaths in the first 48 h after FAV as FAV-related.Results: FAV was performed in 28 fetuses at a median gestational age (GA) of 23 weeks (range, 20-32). FAV was technically successful in 22 (78.6%), of whom 11 were born alive and with intention to treat. Eight (72.7%) resulted in BVC and 3 (27.3%) in univentricular circulation. The rate of FAV-related deaths was 32%. These patients underwent FAV earlier than live-born fetuses (median GA at FAV 22 weeks [range, 20.0-25.0] vs. 24.5 weeks [range, 21.0-32.0], respectively, p = 0.031).Conclusions: A significant proportion of fetuses with CAS who undergo technically successful FAV have BVC postnatally. However, FAV implies a high risk of fetal death, which highly depends on the GA at which this intervention is required. [ABSTRACT FROM AUTHOR]- Published
