Doppler echocardiography

echocardiography /echo·car·di·og·ra·phy/ (-kahr″de-og´rah-fe) recording of the position and motion of the heart walls or internal structures of the heart by the echo obtained from beams of ultrasonic waves directed through the chest wall.

color Doppler echocardiography  color flow Doppler imaging.

contrast echocardiography  that in which the ultrasonic beam detects tiny bubbles produced by intravascular injection of a liquid or a small amount of carbon dioxide gas.

Doppler echocardiography  a technique for recording the flow of red blood cells through the cardiovascular system by means of Doppler ultrasonography, either continuous wave or pulsed wave.

M-mode echocardiography  that recording the amplitude and rate of motion (M) in real time, yielding a monodimensional (“icepick”) view of the heart.

transesophageal echocardiography  (TEE) the introduction of a transducer attached to a fiberoptic endoscope into the esophagus to provide two-dimensional cardiographic images or Doppler information.

Dop·pler echocardiography (dplr)

n.

The use of Doppler ultrasonography to augment echocardiograms that are two-dimensional by allowing velocities to be registered within the echocardiogram.

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
