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.

用于临床评估心肌瘢痕负荷的脉冲消除超声心动图

审查目的

就心肌组织特征而言，超声心动图已被完全放弃，但最近，检测疤痕心肌组织的可能性又得到了恢复。我们回顾了旨在使用超声心动图评估心肌纤维化或瘢痕存在的最新研究。

最近的发现

使用简单且临床上可用的超声，例如脉冲消除法，是标准超声心动图的一种很有前景的补充，用于检测瘢痕心肌组织，主要但不仅限于，在心肌梗塞后患者的情况下。

概括

脉冲消除技术至少在 20 年前就在商用超声机器上可用，可以相当准确地检测由近期或先前心肌梗塞引起的心肌瘢痕组织，其准确性取决于左心室心肌瘢痕的空间分布。在肥厚型心肌病中发现的严重心肌纤维紊乱，也可以通过这种超声方法检测到。
