Doppler echocardiographyDoppler 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

Doppler bidirectional test
Doppler echocardiography - use of Doppler ultrasonography techniques to augment two-dimensional echocardiography by allowing velocities to be registered within the echocardiographic image. Synonym(s): duplex echocardiography
Doppler effect - a change in frequency is observed when the sound and observer are in relative motion away from or toward each other. Synonym(s): Doppler phenomenon; Doppler principle
Doppler flow test
Doppler phenomenon - Synonym(s): Doppler effect
Doppler principle - Synonym(s): Doppler effect
Doppler pulse evaluation
Doppler shift - the magnitude of the frequency change in hertz when sound and observer are in relative motion away from or toward each other.
Doppler ultrasonography - application of the Doppler effect in ultrasound to detect movement of scatterers (usually red blood cells) by the analysis of the change in frequency of the returning echoes.
