2- and 3-Dimensional Myocardial Strain in Cardiac Health and Disease

JACC Cardiovasc Imaging. 2019 Sep;12(9):1849-1863. doi: 10.1016/j.jcmg.2019.01.044.

Abstract

Advances in speckle-tracking echocardiography allowed the rise of deformation imaging as a feasible, robust, and valuable tool for clinical routine. The global or segmental measurement of strain can objectively quantify myocardial deformation and can characterize myocardial function in a novel way. However, the proper interpretation of deformation measurements requires understanding of cardiac mechanics and the influence of loading conditions, ventricular geometry, conduction delays, and myocardial tissue characteristics on the measured values. The purpose of this manuscript is to review the basic concepts of deformation imaging, briefly describe imaging modalities for strain assessment, and discuss in depth the underlying physical and pathophysiological mechanisms which lead to the respective findings in a specific disease.

Keywords: CMR; LV function; deformation; echocardiography; strain.
