Abstract:
Echocardiographic determination of Global Longitudinal Strain (GLS) by manual tracing of endocardial borders is time consuming and operator dependent, whereas visual assessment is inherently subjective. In this paper, the development of a fully automated software using machine learning-enabled image analysis is presented. For a total of 30 patients, apical 4, 2 and 3-chamber views were collected from center that assessed GLS using manual tracing. Manual tracing was done by same user to calculate user inimitability. In addition, datasets were saved in a centralized database, and machine learning-enabled software (AutoStrain, TomTec-Arena 1.2, TomTec Imaging Systems, Unterschleissheim, Germany) was applied for fully automated GLS measurements. AutoStrain measurements were feasible in 95% of studies and the average analysis time was less than 3 sec/ patient. Interclass correlation coefficients and Bland-Altman analysis revealed good ratio’s compared to manual tracking and user to user ratios. Fully automated analysis of echocardiography images provides rapid and reproducible assessment of left ventricular GLS compared to manual tracing.
