The Utility of Myocardial Work in Clinical Practice.

Myocardial work (MW) is a novel technique used in the advanced assessment of left ventricular function. In the past few years, this invasive measure has evolved to become a more attainable noninvasive technique. MW has benefits over left ventricular ejection fraction and global longitudinal strain by speckle-tracking echocardiography, as it includes the afterload-dependent limitation and dynamic myocardial contraction in relationship to various loading conditions.

Specific Considerations for Sonographers When Performing Echocardiography during the 2019 Novel Coronavirus Outbreak: Supplement to the American Society of Echocardiography Statement.

Sonographers need to be familiar with and prepared to implement strategies for reducing the risk of exposure to and transmission of the COVID-19 virus. Strategies to employ can be grouped into three broad categories: (1) whom to scan, (2) where to scan, and (3) how to scan. Whom to scan addresses sonographer strategies for determining essential and emergent scan status.
