Cardiac size and shape in fetuses with absent or reversed end-diastolic velocity of the umbilical artery and severe growth restriction before 34 gestational weeks can be a marker for perinatal survival

In growth restricted fetuses before 34 weeks of gestation, absent or reversed end-diastolic velocity of the umbilical artery (AREDV) increases the odds for fetal death. AREDV is associated with increased placental resistance to blood flow resulting in an increased fetal cardiac afterload with fetal and neonatal consequences.
