AB Assessment  of  left  ventricular  (LV)  wall  motion  traditionally  has  been  performed  through  visual  inspection  of  endocardial  thickening  and  excursion  in  two-dimensional  (2D)  images.  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.
