Figure 1. Example of artificial intelligence global longitudinal shortening (GL‐Shortening) and mitral annular plane systolic excursion (MAPSE) measurements.

A cine 4‐chamber scan is displayed for end‐diastolic (ED) and end‐systolic (ES) phases with detected landmarks overlaid. GL‐Shortening is computed as the percentage shortening of left ventricle (LV) length (from apical to midpoint of 2 valve landmarks). MAPSE is computed as the mean moved distance in millimeters for 2 valve points in each long‐axis image. L is the moved distance of valve point between the ED and ES.
