Dopp·ler ech·o·car·di·og·ra·phy

(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
