Ductus venosus Blood Flow Velocity Waveforms as a Predictor for Fetal Outcome in Isolated Congenital Heart Disease

Abstract

Evaluation of the DV pulsatility is a useful additional variable for predicting the risk for mortality in fetuses with isolated structural CHD, in particular in fetuses with defects of the AV septum and with defects affecting predominantly right ventricular function. As there is no fetal hydrops without abnormal DV, this is another sign for the association of DV and cardiac failure.
