Figure 4
Comparison between echocardiographic and CMR early to late peak ratios and mitral annulus peak longitudinal velocities. Panel a: comparison of the CMR velocity (EMR/AMR) and flow rate (EfMR/AfMR) ratios against the echocardiographic velocity ratio (EUS/AUS). Panel b: comparison between the mitral annulus peak longitudinal velocities estimated from echocardiographic data (E'US) and CMR data (E'MR).
