RETROGRADE DUCTUS VENOSUS ATRIO-WAVE AS A SPECIFIC PREDICTOR OF PERINATAL MORTALITY: A CASE REPORT
As fetal compensation against hypoxemia progresses, the afterload on the heart and peripheral vascular resistance 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...

| Summary: | As fetal compensation against hypoxemia progresses, the afterload on the heart and peripheral vascular resistance 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. |
