LA volumetric parameters and LA global strain
The mean maximum indexed LA volume (LAVi) was 22.2 ± 6.8
ml/m2. The reservoir and contractile LA functions were
the most altered with respect to normal population values. The mean peak
atrial longitudinal strain at the reservoir phase for the total
population was 29.2 ± 8.9%, with a prevalence of abnormal PALS of
58.8% (95% CI : 50.0 – 68.6).
