This subjective method has a high degree of interobserver and intraobserver variability among experienced cardiologists and anesthesiologists.1,2 Over the past few years, the introduction of the concepts of strain and strain rate and the development of new technologies have allowed for the objective quantification of myocardial deformation during the cardiac cycle. These techniques are grouped under the name myocardial deformation imaging and comprise tissue Doppler strain (TDS) and speckle tracking (ST) using either two-dimensional (2DST) or three-dimensional (3DST) echocardiography.
