The advancements in Doppler methodology in the past decade have dramatically changed the way we assess children with heart disease. Techniques to determine pressures, gradients, shunt flows, and regurgitant lesions have shifted the noninvasive studies into areas that were strictly the venue of catheterization a decade ago. The more recent color Doppler

Tissue Doppler echocardiography
Current Opinion in Cardiology, 1999Tissue Doppler echocardiography (TDE) is a relatively recent addition to the diagnostic ultrasonographic examination. This is similar to routine Doppler ultrasonography to assess blood flow, but technologic features focus on lower velocity frequency shifts. Two techniques are used to assess myocardial function: pulsed TDE and color-coded TDE.

Problems in veterinary medicine, 1992
M-mode and two-dimensional echocardiography (2DE) are standard parts of the evaluation of cardiac structure and function in veterinary and human cardiology. Doppler echocardiography, although considered standard in human cardiology, is in its infancy in veterinary cardiology.

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
