Detection of chronic coronary artery disease (CAD) via visual assessment of wall motion abnormality is subjective and variable (1). Tissue Doppler echocardiography (TDE) and tissue Doppler-based strain echocardiography (TDSE) allow quantification of regional myocardial mechanics (2, 3). The concept of using regional mechanics for stress echocardiography is appealing because rest or inducible ischemia ultimately manifests as abnormal regional mechanics.Tissue Doppler echocardiography and TDSE have offered several options for quantifying inducible ischemia (4, 5). Quantification appears to be superior to traditional visual assessment of wall motion and may help novice echocardiographers in interpretation of stress echocardiograms (6). The primary parameter used to track changes in regional mechanical behavior is systolic displacement (tissue velocity) or deformation (systolic strain rate or strain).
