Left ventricular strain is sensitive to systolic dysfunction, independent of ejection fraction, such as in those with heart failure with preserved ejection fraction (HFpEF). However, several distinct strain components are routinely measured, most commonly globally averaged longitudinal, circumferential and radial. However, global strains can be measured on the endocardium, epicardium or averaged across the wall thickness with large differences in normal/pathologic values at each location and with distinct performance in terms of identification of systolic dysfunction or outcomes prediction in heart failure.
What is the current state/problem in practice? Currently, left ventricular strains are not measured or reported with consideration of layer-dependence (endocardium to epicardium) of values. What is the ideal state/ if the problem is gone? Ideally, left ventricular strains would be reported with clear specification of measurement locations, and with the consideration of added value of layer-specific strains.
This CME activity will raise awareness of layer-dependence of left ventricular strains and the potential added value of consideration of layer-specific assessment.
1. Learners should be aware that distinct layer-specific left ventricular strains can be used measured for detection of systolic dysfunction.
2. Learners should be aware of the capabilities of their strain analysis software and should specify the locations of strain analysis (e.g. is global longitudinal strain (GLS) measured on the endocardial surface or the average of all locations over the wall thickness).
