Despite recent advances in clinical imaging, echocardiography remains as the most accessible
and reliable noninvasive. Since knowledge of left ventricular systolic function remains so critically
important in determining prognosis; every effort should be made to prevent subjective estimations.
The advent of strain imaging echocardiography now offers a readily available and portable
imaging tool that not only offers an objective characterization of myocardial dynamics; but also allows
for early detection of subclinical left ventricular dysfunction. This review outlines the basic
concepts of strain imaging to better understand the mechanism of myocardial function as well their
applicability in the least common cardiac diagnosis among current clinical practice.
