[Doppler tissue imaging in the assessment of dilated cardiomyopathy].
Doppler myocardial tissue imaging is a recent technique of objective assessment of wall motion by real time measurement of intra-myocardial velocities. This technique is being evaluated in patients with dilated cardiomyopathy. Doppler myocardial tissue imaging has been used for the quantification of dobutamine stress echocardiography, for the detection of an ischaemic aetiology in patients with dilated cardiomyopathy and for non-invasive estimation of left ventricular filling pressures. At the present time, the recordings have to be analysed a posteriori and only a small number of centres have acquired expertise of these techniques at rest or during stress. Standardisation of a posteriori procedures of image processing and validation of pertinent parameters have yet to be established in this pathology.
