Fig. 1

Box plots of LV PV loop parameters obtained from CMR and TTE. (a) End-systolic elastance (E_es); (b) Arterial elastance (E_a); (c) Ventricular–arterial coupling (VAC); (d) Stroke work (SW); (e) Pressure–volume area (PVA); (f) Work efficiency (WE). Values obtained from CMR and TTE are compared for each parameter.
