(dop'lĕr),
use of Doppler ultrasonography techniques to augment two-dimensional echocardiography by allowing velocities to be registered within the echocardiographic image. See: duplex ultrasonography, Doppler ultrasonography.

Doppler echocardiography

Etymology: Christian J. Doppler
a technique in which Doppler ultrasonography is used to evaluate the direction and pattern of blood flow within the heart.

Doppler echocardiography

Doppler cardiac ultrasonography Cardiology A noninvasive imaging modality for assessing hemodynamics, based on the Doppler effect on ultrasound-US waves; DE estimates transvalvular gradients and calculates valve–aortic, mitral area; it has been used to evaluate congenital shunts, atrial septal defect, patent ductus arteriosus, left ventricular inflow–eg parachute deformity, cor triatriatum and outflow–eg congenital aortic valve stenosis, subaortic stenosis, hypertrophic obstructive cardiomyopathy obstruction, atrioventricular valve regurgitation and other lesions

In present study, we also evaluated CFR, the magnitude of the increase in blood flow at maximal coronary vasodilation, by using transthoracic Doppler echocardiography as a reliable and reproducible way to assess CFR (30) and found that there is a coronary microvascular endothelial dysfunction in MetS patients.
The mean (SD) plasma concentration of N-terminal proBNP was 59 (51) pmol/L in the group of patients with normal SFN and DFN by Doppler echocardiography and without certain disorders, abnormalities, or drug treatment (n = 39).

Mitral inflow was obtained by pulsed-wave Doppler echocardiography with the sample volume between mitral leaflet tips during diastole, and mitral annulus velocities were obtained from the septal and lateral annulus by tissue Doppler imaging.
