[Tissue Doppler echocardiography: a new stage in the study of myocardial function]

Tissue Doppler echocardiography is a new technique that allows selective visualization and measurement of myocardial velocities, affording a new perspective on cardiac function. It has been showing promising and exciting preliminary results on coronary artery disease, hemodynamics, cardiomyopathies, right ventricular and aortic diseases and arrhythmias, opening a new era in the analysis of regional myocardial function.
