Fetal Dual Doppler Echocardiography
Dual Doppler echocardiography is a recently developed technique performed using an instrument with two separate sample gates, allowing simultaneous recording of signals from two locations. We describe the use of dual Doppler echo cardiography to assess fetal cardiac rhythm. Fetal arrhythmias are common and encountered in 1 to 2% pregnancies. They often resolve spontaneously and do not require ...
متن کاملDOPPLER ECHOCARDIOGRAPHY Detection and quantitation of constriction of the fetal ductus arteriosus by Doppler echocardiography
Pulmonary hypertension may occur in the fetus in the presence of constriction of the ductus arteriosus. The feasibility of detection and quantitation of fetal ductal constriction by Doppler echocardiography was assessed in an animal preparation in which ductal constriction was created in the fetal lamb with a variable ligature causing varying degrees of fetal pulmonary hypertension (fetal pulmo...
متن کاملFetal cardiac time intervals determined by Doppler echocardiography.
One-hundred and eleven Doppler echocardiographic examinations were performed on 88 normal fetuses, ranging from 16 to 41 weeks of gestation. Aortic and pulmonary maximal velocity (MV), acceleration time (AT), ejection time (ET), MV/AT (acceleration velocity: AV) and AT/ET ratio in systole were assessed on each blood flow velocity waveform. Aortic MV and pulmonary MV correlated well with gestati...
متن کاملFetal Echocardiography Indications: A Single- Center Experience
Background Congenital heart disease (CHD) is the most common lethal congenital anomaly. Early diagnosis of CHD by fetal echocardiography based on maternal and fetal indications is important and lifesaving. The aim of study was to assess the referral aspects of pregnant women to pediatric cardiologist. Materials and Methods This was a retrospective cross-sectional study on 250 documents of refer...
متن کاملColor and power Doppler combined with Fetal Intelligent Navigation Echocardiography (FINE) to evaluate the fetal heart
OBJECTIVE To evaluate the performance of color and bidirectional power Doppler ultrasound combined with Fetal Intelligent Navigation Echocardiography (FINE) in examining the fetal heart. METHODS A prospective cohort study was conducted of fetuses in the second and third trimesters with a normal heart or with congenital heart disease (CHD). One or more spatiotemporal image correlation (STIC) v...
