Illustration of the methodology for LA function analysis. a, b Left atrial contours from a 4-chamber view and longitudinal strain and strain rate related curves of a subject from the Obese-Type 2 diabetes (ObT2D) group. Ro example of a radius used for the computation of the radial motion fraction. Decomposition of the radial motion fraction into MV centric (cMr, towards the mitral valve center) and MV corrected perpendicular (pMr, MV corrected perpendicular radial motion fraction) components. c, d Sl R reservoir longitudinal strain, Sl C conduit longitudinal strain and Sl A La contraction longitudinal strain, SRL S′ reservoir longitudinal strain rate, SRl E′ conduit longitudinal strain rate and SRl A′ LA contraction longitudinal strain rate
