Two-dimensional (2D) echocardiography is the most common imaging modality used to assess left ventricular (LV) myocardial function. Although the studies revealed useful conclusions, there are some limitations with the conventional measurement of ejection fraction. Two dimensional (2D) strain imaging is newer echocardiographic technique which is utilized for the evaluation of quantitative regional ventricular functions. Velocity vector imaging based- 2D strain imaging is the most recent technology with a few advantages sourced by its software. This review introduces a novel 2D strain imaging technology, explains its fundamental concepts and discusses clinical applications with all the major advantages and limitations.
二维（2D）超声心动图是评估左心室（LV）心肌功能最常用的成像方式。尽管这些研究得出了有用的结论，但传统射血分数测量存在一些局限性。二维（2D）应变成像是一种较新的超声心动图技术，用于评估局部心室功能的量化。基于速度矢量成像的二维应变成像是最新的技术，其软件具有一些优势。本综述介绍了一种新型二维应变成像技术，解释其基本概念，并讨论其临床应用以及所有主要优势和局限性。
