Clinical Utility of Ductus Venosus Flow in Fetuses With Right‐Sided Congenital Heart Disease

Abnormal ductus venosus flow is associated with fetal compromise and can be present in right‐sided congenital heart disease. We hypothesized that the ductus venosus flow pattern in fetuses with obstructive right‐sided congenital heart disease will have abnormal flow at baseline. Those with nonobstructive disease will have normal flow at baseline. We further hypothesized that abnormal ductus venosus flow will predict fetal compromise.
