Deformação = Strain = Dúvidas


Area strain is determined as the percentage decrease in the size of endocardial (or mid-myocardial) surface area, defined by vectors of longitudinal and circumferential deformation at end-systole from its original area at end-diastole [6]. Principal strain represents the major direction and magnitude of the deformation in which no shear strain occurs. It reflects longitudinal, circumferential, and torsional deformation; therefore, it can represent dynamic 3D movements of the left ventricle
