Tissue Doppler imaging (TDI) and its derived technologies (Strain, Strain Rate) are increasingly important for risk stratification and functional assessment in coronary heart disease and heart failure.

Supports TDI integration for CAD and HF assessment; extends imaging literature while leaving prospective outcome validation open.
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 (2D) Strain.
