Two-Dimensional Echo Doppler Characterization of Right and Left Ventricular Flow in the Human Fetus
Ultrasound accompanied by advanced technology has allowed noninvasive assessment of the human fetal heart and circulation. Enormous progress has been made in antenatal diagnosis of congenital heart disease and in the recognition of abnormal flow patterns that are related to severe disturbances of the fetal circulation. The purpose of this investigation was to extend our information about the fetal circulation by obtaining quantitative data on combined ventricular output and the relationship between right and left ventricular output in a longitudinal study of the normal human fetus.
