OC12.06: Outcome of prenatal ventricular size discrepancy in cases without coarctation

Abstract

Oral communication abstractsResults: A total of 444 ultrasound evaluations were performed on 119 CHD fetuses, with a median of 2 measurements per fetus. CHD fetuses showed a small head at diagnosis (BPD −1.32 ± 0.99 z scores, HC −0.79 ± 1.02 z-scores), maintained throughout gestation (figure a). UtA and UA Doppler showed an increase towards the end of pregnancy, whereas no changes were observed in MCA or cerebroplacental ratio (CPR) with gestational age (figure b). Conclusions: CHD fetuses showed smaller head biometries since the second trimester of pregnancy, suggesting an early insult that persists throughout gestation. UtA and UA Doppler resistance increased, which may indicate co-existing placental impairment in CHD cases.Supporting information can be found in the online version of this abstract
