Transthoracic echocardiography is the primary cardiac imaging modality for the detection of Cancer Therapeutics‐Related Cardiac Dysfunction (CTRCD) through evaluation of serial changes in left ventricular ejection fraction (LVEF). However, LVEF assessment by standard methods including 3D Echo has important limitations including the fact that reduction in LVEF occurs late in the process of CTRCD. In contrast, by detecting early myocardial change, myocardial strain or deformation imaging has evolved to be a preferred parameter for detecting CTRCD. Peak systolic global longitudinal strain (GLS) by speckle‐tracking echocardiography (STE) has become an important prechemotherapy parameter that can independently predict subsequent adverse cardiac events as these abnormalities typically precede reduction in LVEF. While an absolute GLS measurement may be informative, a 10%‐15% early reduction in GLS by STE appears to be the most useful prognosticator for cardiotoxicity while on therapy. In this paper, we present a current systematic literature review of application of myocardial strain imaging in cancer patients performed following PRISMA guidelines using electronic databases from MEDLINE, Embase, and SCOPUS Library from their inception until June 11th 2020. This review demonstrates the incremental value of myocardial deformation imaging over traditional LVEF in detection and its clinical implication in management of CTRCD.
