After myocardial infarction, treatment aims at restoring normal cardiac function, which is more likely if scar transmurality is limited. Cardiac wall motion is complex and difficult to objectively analyze. We have used a feature tracking software to measure radial and longitudinal velocity, displacement and strain to evaluate scar segments in patients after ST-elevation myocardial infarction. The method could separate segments with various scar transmurality as determined with gadolinium enhancement.
