[Use of tissue Doppler echocardiography].
Tissue Doppler Echocardiography (TDE) is a new noninvasive technique which shows myocardial tissue by color-mapping. It's based on the color Doppler and used to assess in a direct way left ventricular systolic and diastolic function. It helps to measure velocities, acceleration and energy signal within the myocardial wall. The transmural gradient of velocities can be calculated too. TDE can be used to detect regional systolic dysfunction due to myocardial ischemia and viable myocardium. It gives specific view of intracardiac structures and is useful for identification tumors, thrombus and vegetations.
