Bland–Altman plots comparing PV loop parameters obtained from CMR and TTE. Each panel shows the mean difference (bias) between methods and the 95% limits of agreement: (a) End-systolic elastance (Ees); (b) Arterial elastance (Ea); (c) Ventricular–arterial coupling (VAC); (d) Stroke work (SW); (e) Pressure–volume area (PVA); (f) Work efficiency (WE).
