VENC-CMR vs. TEE. Figure 4A and C: Correlation and agreement between VENC-CMR and TEE measurements of peak e-wave velocities (r = 0.61, P < 0.001, mean difference 0 ± 10 cm/s). Figure 4B: Correlation for measurements of peak a-wave velocities between VENC-CMR and TEE (r = 0.71, P < 0.001). Figure 4D: Mean underestimation of 10 ± 15 cm/s for peak a-wave velocities (P < 0.05) by VENC-CMR compared to TEE. On Bland-Altman plots, middle continuous line indicates mean bias, and dashed lines above and below indicate 95% confidence intervals.
