Abstract
Doppler echocardiography is the study of low magnitude echoes from red blood cells which are neglected in the conventional, imaging echocardiography. It helps to provide flow and pressure data from the cardiac chambers and the great vessels, thus supplementing the anatomic data provided by the imaging echocardiography. Several Doppler systems, namely, pulsed Doppler, continuous wave Doppler and high pulsed rate frequency Doppler are available, each with its own advantages and disadvantages. Qualitative and quantitative estimates of intracardiac shuntssemilunar and atrioventricular valve insufficiency and stenotic lesions and determination of flow and pressure from the heart can be made by Doppler echocardiography. Doppler should be performed in conjunction with imaging echocardiography and is a useful adjunct to it.
