Color doppler echocardiography
International Journal of Cardiac Imaging, 1988Color Doppler flow mapping is a useful new imaging modality which provides near real-time information about the direction and character of intracardiac flows. Color Doppler is especially useful in the diagnosis and quantitation of valvular regurgitation, and in the detection of intracardiac shunts. Color Doppler is a useful adjunct to CW Doppler in the

Pediatric Cardiology, 2002
We describe concepts important in the clinical application of continuous wave, pulsed wave, and color Doppler flow imaging. In the second half of this manuscript, the application of these tools in pediatric echocardiography is addressed.

Fetal Doppler Echocardiography
Clinical Obstetrics and Gynecology, 1989Les 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 ...

Usefulness of Echocardiography and Doppler Echocardiography in Endomyocardial Fibrosis
Journal of the American Society of Echocardiography, 2000Our goal was to demonstrate the usefulness of echocardiography and cardiac Doppler echocardiography (echo-Doppler) in the diagnosis of endomyocardial fibrosis, an unusual restrictive cardiomyopathy in Argentina.Between 1980 and 1998, we studied 10 women (aged 27 to 58 years) with endomyocardial fibrosis confirmed by surgery and/or endomyocardial biopsy.

Abstract Doppler examination is an integral part of the echocardiogram. Current systems are equipped with spectral Doppler in continuous wave mode (offering measurements of high velocities with limited spatial specificity due to integration of signal along the scan line), pulsed wave mode (high spatial specificity with maximal recordable

The addition of Doppler hemodynamic studies to two-dimensional echocardiographic imaging has added specificity to the noninvasive diagnosis of some congenital lesions, and it has provided new hemodynamic information in unsuspected areas. As a quantitative tool, Doppler is used to estimate gradients in stenotic lesions, blood flow in the heart and great

Doppler echocardiography in shocked patients
Current Opinion in Critical Care, 2013To reiterate the necessity of integrating echocardiography in the management of shocked patients and to propose a step-by-step functional evaluation of hemodynamics proven to optimize hemodynamic monitoring and to adapt the treatment.Echocardiography has become the cornerstone to hemodynamic monitoring.

Gabor spectra for Doppler echocardiography
Medical & Biological Engineering & Computing, 1998Doppler echocardiography on current ultrasonography machines makes use of short-time Fourier spectrograms (STFTs) to display the patterns of blood velocities in the heart chamber. From these sonologists infer the functional parameters, such as valve area, that have pathological significance.

Pulsed doppler fetal echocardiography
Journal of Clinical Ultrasound, 1985AbstractPulsed Doppler echocardiography (PDE) has proven value in the examination of the infant or child with known or suspected congenital heart disease. In order to assess how PDE might be useful in the evaluation of the infant in utero, we reviewed our experience with this technique used in combination with both cross‐sectional and M‐mode ...
