Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect .
The anterior interventricular sulcus and posterior interventricular sulcus extend from the base of the ventricular portion to a notch, the notch of cardiac apex, (or incisura apicis cordis) on the acute margin of the heart just to the right of the apex.
Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care.

A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
The terms tissue Doppler imaging (TDI) and tissue velocity imaging (TVI) are usually synonymous with TDE because echocardiography is the main use of tissue Doppler. Like Doppler flow, tissue Doppler can be acquired both by spectral analysis ( spectral density estimation ) as pulsed Doppler [ 1 ] and by the autocorrelation technique as colour ...
Numerical manipulation of Doppler parameters obtain during routine Echocardiography has been extensively utilized to non-invasively estimate intra-cardiac pressures, in many cases removing the need for invasive cardiac catheterization. [1] Echocardiography uses ultrasound to create real-time anatomic images of the heart and its structures.

Doppler echocardiography is the use of Doppler ultrasonography to examine the heart. [13] An echocardiogram can, within certain limits, produce an accurate assessment of the direction of blood flow and the velocity of blood and cardiac tissue at any arbitrary point using the Doppler effect.
