3D-Wall Motion Tracking: Measuring Myocardial Strain with 3D

The study of myocardial mechanics with echocardiography has been enhanced in the last two decades by strain analysis with tissue Doppler and 2D speckle tracking technologies. These methods offer a limited approach because of the angle and plane limitations. 3D speckle tracking is expected to overcom...

Summary:The study of myocardial mechanics with echocardiography has been enhanced in the last two decades by strain analysis with tissue Doppler and 2D speckle tracking technologies. These methods offer a limited approach because of the angle and plane limitations. 3D speckle tracking is expected to overcome these limitations by using a three-dimensional approach. In this chapter, we will review the background and technical aspects of this technology; we will propose an acquisition protocol and explain the wide options of processing available; the different strain parameters will be defined and explained with a wider explanation of new indexes such as area strain or 3D strain; we will make a brief review of the clinical applications available in the current literature;and also the limitations and possible future improvements will be described.
