2. Figure 1
Changes in left ventricular (LV) volume and ejection fraction (EF) in the patients with (black circles, group A) and without (white circles, group B) LV dysfunction. LVEDVI, Left ventricular end-diastolic volume index; LVESVI, left ventricular end-systolic volume index. ∗∗∗Before versus after surgery and ###group A versus B denote significant differences (P < .001).

Changes in left ventricular (LV) performance in patients with (black circles, group A) and without (white circles, group B) LV dysfunction. Ees, End-systolic elastance; Ea, effective arterial elastance; Ea/Ees, ventriculoarterial coupling; SW/PVA, stroke work/pressure–volume area ratio. ∗∗∗Before versus after surgery and ###group A versus B denote significant differences (P < .001).
