Noninvasive Assessment of Myocardial Work in Children

The noninvasive assessment of ventricular function is an ongoing challenge, with new tools and measurements always being considered and tested. The noninvasive assessment of myocardial work via the pressure-strain relationship is one of the newer tools proposed to evaluate ventricular systolic function. However, prior to using any new tool, one should understand its properties, utility, and limitations. In this commentary we focus on the noninvasive assessment of myocardial work via the pressure-strain relationship from a pediatric point of view. We address the current knowledge and limitations and propose future directions to better understand this tool. •The pressure–strain relationship can be used as a surrogate for myocardial work.•This noninvasive surrogate of myocardial work is validated in adults, not children.•Limitations, many specific to children, must be addressed prior to its utilization.•The technique is far from ready for use in children.
