Utility of Ductus Venosus Blood Flow in the Study of Cardiac Function in Fetuses with Intracardiac Echogenic Focus

Abstract

Purpose. The purpose of this study was to investigate fetal ductus venosus (DV) wave velocities, DV velocity ratios, and DV diastolic time intervals to derive additional information on fetal cardiac function in the presence of an intracardiac echo-genic focus (IEF).
