As fetal compensation against hypoxemia progresses, the afterload on the heart increases,
peripheral vascular resistance also increases. Eventually, the right heart fails, which is transmitted to the
fetal venous system, causing decreased flow during late diastole or atrial contraction and increased
resistance in the ductus venosus and inferior vena cava. The ductus has forward flow during atrial
contraction, the disappearance of which is always pathologic. This is a report of a case of retrograde
ductus venosus atrio-wave in a fetus referred with decreased movement for fetal assessment.
