Figure 1.

The figure illustrates phasic LA volumes, function (left), and longitudinal strain (right) corresponding to 1 cardiac cycle. (a and b) Feature tracking CMR imaging of LA in a 2- and 4-chamber view. (c) Vmax—maximum LA volume, Vmin—minimum LA volume, and VpreA—LA volume before atrial contraction, respectively. On the longitudinal strain curve (right), Smax—maximum LA longitudinal strain and SpreA—LA longitudinal strain before atrial contraction. Abbreviations: CMR, cardiac magnetic resonance; LA, left atrium.
