Figures

• 

  Fig. 1. Accuracy of echo-derived LVEF based on CMR as gold standard. Bland–Altman plot for comparison of LVEF by echocardiography and CMR; mean difference between LVEF derived by echo and MRI = − 0.0152, SD = 0.37, P = 0.043

• 

  Fig. 2. Accuracy of RV FAC by echocardiography based on CMR as gold standard. Bland–Altman plot for comparison of RVEF by echocardiography (RV FAC) and Cardiac MRI; mean difference between RVEF derived by echo and MRI = 0.0237, SD = 0.021, P = 0.000

• 

  Fig. 3. Downward slope of RV GLS changes over time; before, early and late after PVR, Baseline to early changes: P = 0.052, Baseline to late and early to late changes: P = 0.000: significant P < 0.05

• 

  Fig. 4. Downward slope of LV GLS changes over time; before, early and late after PVR, Baseline to early changes: P = 0.27, baseline to late: P = 0.000, Early to late: P = 0.005,: significant P < 0.05

• 

  Fig. 5. Upward slope of RV FAC changes over time; before, early and late after PVR. Baseline to early postop changes was not significant: P = 0.782, Late relative to early postop was significant: P = 0.001, late postop compared to baseline was not significant: P = 0.002

• 

  Fig. 6. Upward slope of LVEF changes over time; before, early and late after PVR. Late postop relative to early postop was significant: P = 0.007, but late postop compared to baseline and baseline to early postop changes were not significant: P = 0.4; lvef2: early LVEF, lvef3: late LVEF
