Late gestation predictors of a postnatal biventricular circulation after fetal aortic valvuloplasty
Why the study?
Predicting which fetuses will achieve a biventricular circulation after fetal aortic valvuloplasty remains challenging, and late gestation echocardiographic predictors could improve parental counseling.
Do specific late gestation echocardiographic parameters predict postnatal biventricular circulation in fetuses undergoing fetal aortic valvuloplasty for severe aortic stenosis?
Population
96 liveborn patients who underwent fetal aortic valvuloplasty with late gestation echocardiography available
Design
Cohort study
Follow-up
Neonatal discharge

Implication
Late-gestation echo predictors may refine BiV counseling after FAV; leaves open prospective validation before wider adoption.
Structured PICO
Do specific late gestation echocardiographic parameters predict postnatal biventricular circulation in fetuses undergoing fetal aortic valvuloplasty for severe aortic stenosis?
P
Population
96 liveborn patients who underwent fetal aortic valvuloplasty (FAV) for severe aortic stenosis (AS) and had late gestation echocardiography available (treated between 2000-2017).
I
Intervention
Fetal aortic valvuloplasty (FAV) followed by late gestation echocardiography assessment
O
Outcome
Biventricular (BiV) circulation at the time of neonatal dischargehard clinical
Late gestation echocardiographic parameters, including LV long axis z-score and anterograde aortic arch flow, independently predict the achievement of a postnatal biventricular circulation after fetal aortic valvuloplasty.
