Doppler fetal echocardiography in endocardial fibroelastosis

Obstetrics & Gynecology, 2001
Endocardial fibroelastosis is a congenital heart disease known to cause congestive heart failure in early infancy. We report a case using new modalities for early prenatal diagnosis of endocardial fibroelastosis causing fetal heart failure.A multipara with two children, who died of endocardial fibroelastosis, was referred for fetal echocardiography at ...

Doppler-The Fetal Circulation

Clinical Obstetrics and Gynecology, 1997
Intrauterine growth restriction is associated with abnormalities in the fetal circulation. These abnormalities are currently best understood in the umbilical arterial and venous systems. Changes in intracardiac velocities are more variable as well as more difficult to detect.

Fetal Doppler Echocardiography

Clinical Obstetrics and Gynecology, 1989
Les auteurs rappellent les particularites du systeme cardiovasculaire fœtal et donnent les indications de son exploration par echographie Doppler. La technique de l'examen du cœur fœtal est ensuite decrite ainsi que les differents traces obtenus. Le chapitre se termine par les applications possibles de cet examen au diagnostic in utero des anomalies ...

Fetal Doppler Assessment in Neonatal Care: Analysis of Fetal Doppler Abnormalities and Neonatal Outcomes

NeoReviews, 2019
Fetal Doppler ultrasonography provides an effective and noninvasive approach to identify circulatory abnormalities in the maternal-fetal circulation. It is invaluable to assess the hemodynamic status of the fetus under a wide range of physiologic, infectious, and abnormal anatomic conditions.

The use of colour Doppler in fetal echocardiography

International Journal of Cardiology, 1990
Doppler colour flow mapping provides a non-invasive method for studying patterns of blood flow in the cardiovascular system. We undertook a prospective study using this technique in order to document normal and abnormal patterns in the human fetus. A group of 50 consecutive normal fetuses were examined with colour flow mapping.

Ultrasonic Doppler inspection of the fetal heart

American Journal of Obstetrics and Gynecology, 1966
I N T H E M I D D L E Of the nineteenth century, a professor of physics at the University of Vienna propounded a theory which bears his name. Christian Doppler noted that the apparent frequency of waves depends on the relative motion of the wave source and the observer.

Fetal Doppler echocardiography in pulmonary atresia

Journal of Ultrasound in Medicine, 1993
The prenatal diagnosis of pulmonary atresia is of particular importance because the affected neonate may be dependent on ductal blood flow to the lung, requiring urgent administration of prostaglandins. We review eight cases studied by ultrasonography in utero. Severe tricuspid regurgitation was present in six fetuses.

Doppler velocimetry in the evaluation of fetal hypoxia

Journal of Perinatal Medicine, 2001
Knowledge of fetal hemodynamic physiology has developed enormously during the last two decades due to Doppler ultrasound. Some of this knowledge has been utilized for routine surveillance of high-risk pregnancies. The prediction of fetal hypoxia before the development of life lasting sequel is of major importance, especially in the very premature case ...

Doppler assessment of the fetal venous system

Seminars in Perinatology, 2001
This article describes the achievements in Doppler measurements of the fetal venous circulation with emphasis on the clinical impact of these techniques. In rhesus isoimmunization, fetal venous flow assessment gives useful information on the fetal haematologic condition and on the impact of blood transfusion.
