The application of tissue Doppler imaging (TDI) has shown remarkable growth in clinical practice during the
past years, especially, in risk stratification of patients with coronary heart disease or heart failure (systolic and diastolic).
TDI systolic velocities have been used to detect impaired systolic function in patient with coronary artery disease and
heart failure. Important patents were reported in the last years. Main Future development is the application of threedimensional
echocardiography with TDI and other technologies derived from TDI, as Strain, Strain Rate and Twodimensional
Coronary artery disease, echocardiography, heart failure, tissue doppler imaging.
