E': early mitral septal velocity in (m/sec²); E/E': ratio of Early mitral velocity divided by early mitral septal velocity; E/A-ratio: ratio of Early mitral velocity divided by atrial mitral velocity. * MRI and echocardiography parameters were compared using the paired t-test, mean differences, 95% confidence intervals (95% CIs) and p-values were given. * p < 0.05.
