Response to “Minimal Detectable Change and Reproducibility of Echocardiographic Strain: Implications for Clinical Practice”

We thank Dr. Pressman for his interest in our paper “Deep Learning for Improved Precision and Reproducibility of Left Ventricular Strain in Echocardiography: A Test-Retest Study”1 and agree with his suggestion that similar methods should be used in future studies to determine the real reproducibility of global longitudinal strain (GLS). A test-re test study design including repeated acquisitions, multiple observers, and statistical methods estimating the minimal detectable change (MDC) is essential for obtaining the most accurate knowledge of clinically relevant reproducibility.
