Left Ventricle Longitudinal Deformation Assessment by Mitral Annulus Displacement or Global Longitudinal Strain in Chronic Ischemic Heart Disease: Are They Interchangeable?

Longitudinal deformation by global strain or MA displacement correlated well with myocardial infarct mass and could discriminate between different extents of myocardial infarctions. Global longitudinal strain tended to be better, especially for the identification of the smallest infarcts.
