Left ventricular mechanical dyssynchrony (LVMD) is one of the manifestations of abnormal left ventricular motion. And the measured indexes related to LVMD are the indexes derived from left ventricular strain, which can predict the response to cardiac resynchronization therapy and the prognosis of the patients with acute myocardial infarction. The premise of LVMD diagnosis is to measure segmental strains of left ventricle accurately. As an emerging cardiac imaging technology, cardiac magnetic resonance (CMR) can accurately measure the strain of each left ventricle segment, which makes it valuable in both clinic and scientific research. In this article, the mechanism of LVMD, the measurement by CMR and its clinical application to heart diseases are reviewed.

Key words: left ventricular mechanical dyssynchrony (LVMD), cardiac magnetic resonance (CMR), acute myocardial infarction (AMI), cardiac resynchronization therapy (CRT)
