Purpose of Review: Echocardiography has been completely abandoned as far as myocardial tissue characterization is concerned, but recently, the possibility to detect scarred myocardial tissue has been revived. We review the most recent studies aiming to assess the presence of myocardial fibrosis or scar using echocardiography. Recent Findings: The use of a simple and clinically available ultrasound, such as method pulse-cancellation, is a promising add-on to standard echocardiography for the detection of scarred myocardial tissue, mostly, but not only, in the setting of post-myocardial infarction patients. Summary: Pulse-cancellation technique, available since at least 20 years ago on commercial ultrasound machines, is reasonably accurate to detect myocardial scar tissue caused by recent or prior myocardial infarction, the accuracy varying depending on the spatial distribution of myocardial scars in the left ventricle. Severe myocardial fibers disarray, as found in hypertrophic cardiomyopathy, can also be detected by this ultrasound method.
