TTE: trans-thoracic echocardiography; VTI: velocity time integral; PLR: passive leg raising.

Variations of mean LV-LS after a passive leg raising.
+ 11% (±38%) in the PLD- group versus + 19% (±31%) in the PLD+, p = 0.08 (Kruskal-Wallis test). Dark line represents the median for each group.

Compared LV-LS variations in-between baseline and PLR, in PLD+ patients versus PLD- patients, using a linear model for repeated measures, p = 0.13.
