Identification of fetal atrial flutter by Doppler tissue imaging.
A26-year-old woman presented at 33 weeks of gestation with a singleton fetus with tachycardia. A complete fetal echocardiogram revealed a structurally normal fetal heart without signs of hydrops. The fetal heart rate was between 200 and 220 bpm. Evaluation of the rhythm with pulsed Doppler and M-mode scanning was not definitive. Fetal Doppler tissue imaging color M-mode scanning was performed b...
متن کاملDoppler colour flow imaging of fetal intracerebral arteries relative to fetal behavioural states in normal pregnancy.
In 14 normally developing term fetuses, the relationship between the blood flow velocity waveforms at cerebral arterial level (internal carotid artery, anterior, middle and posterior cerebral artery) and fetal behavioural states was studied using Doppler colour flow imaging. Behavioural state dependent changes in absolute flow velocities occurred in all vessels, except for the middle cerebral a...
متن کاملAssessment of fetal cardiac function using tissue Doppler techniques.
OBJECTIVE Tissue Doppler echocardiography is being increasingly used in fetal medicine as a clinical and research tool. The objective of this study was to review the current status of tissue Doppler imaging (TDI) techniques applied to the fetus. METHODS Fetal cardiac function was evaluated using spectral and color TDI modes in normal fetuses and in several clinical conditions. RESULTS Annul...
متن کاملPrenatal Diagnosis of Fetal Arrhythmias and Assessment of Autonomic Nervous System Activity by Fetal Magnetocardiography
Magnetocardiography (MCG) is a technique that enables the noncontact, noninvasive measurement of electrocardiographic phenomena, and fetal magnetocardiography (FMCG) is extremely useful for the analysis of fetal electrocardiographic phenomena. We have used FMCG for the diagnosis and treatment of a range of fetal arrhythmias, and to perform comparative studies of autonomic nervous system activit...
متن کاملEchocardiographic Assessment of Left Ventricle Torsion by Tissue Doppler and Velocity Vector Imaging
Introduction Left ventricular (LV) twist is believed to store potential energy and plays an important role in generating diastolic suction. Recent advances in echocardiography techniques have allowed quantification of LV twist. The aim of the present study was to compare LV twist and torsion in healthy human subjects determined by velocity vector imaging (VVI) and tissue Doppler imaging (TDI) a...
