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 measurement
Doppler phenomenon - Synonym(s): Doppler effect
Doppler principle - Synonym(s): Doppler effect
Doppler probe
Doppler pulse evaluation
Doppler scope
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.

At this time, a cardiac duplex echocardiography was performed that showed echodense mobile masses in the right atrium (RA) measuring 1.8 cm x 1.2 cm and multiple masses in the right ventricle (RV) septal and lateral wall and in the left ventricle (LV) septal wall with dimensions 2.7 cm x 0.8 cm [Figure 1].{Figure 1}
Nevertheless, a heart defect with right-to-left-shunt was suspected but was later excluded by duplex echocardiography at the Children's Cardiology Department of the University of Bonn.
