Physicians Pre-Conference: Cardiac Function-Strain Imaging! Comparison of techniques and clinical applications

Strain Imaging! Comparison of techniques and clinical applications

Video Transcription

Video Summary

The speaker reviews cardiac strain imaging across echocardiography and CMR, including myocardial tagging, speckle tracking, dense, SENC, and feature tracking. Feature tracking is highlighted for ease of use and retrospective analysis, but results vary by software, contouring, and image quality. Strain helps detect regional and subclinical dysfunction and improves prognosis beyond ejection fraction and LGE in many studies. Normal GLS is about −20%, and adequate temporal resolution is important, with 30–40 frames per cycle preferred. The talk concludes that strain is promising but needs standardization and may expand to right and atrial chambers.
