Figure 3

In case 1, reservoir (r), conduit (e), and contractile (a) strains and strain rates were 41.1%, −25.6%, and −15.5%, and 1.68 s−1, −2.0 s−1, and −2.2 s−1, respectively. On the other hand, case 2 had lower reservoir, conduit, and contractile strains and strain rates (22.1%, −13.9%, and −8.2%, and 1.02 s−1, −0.70 s−1, and −0.82 s−1, respectively). Abbreviations: LAS, left atrial strain; LASR, left atrial strain rate.
