Table 1 Weighted-kappa agreement between Vp-echo and MRI Vp-MRI-DQ and Vp-MRI-LR.

From: High-temporal velocity-encoded MRI for the assessment of left ventricular inflow propagation velocity: head-to-head comparison with Color M-mode echocardiography

  Vp-MRI-DQ Vp-MRI-LR
  < 45/55 cm/s ≥ 45/55 cm/s < 45/55 cm/s ≥ 45/55 cm/s
Vp-echo < 45/55 cm/s 23 6 23 7
  ≥ 45/55 cm/s 3 33 3 32
  1. Age-related cut-off values were used to classify elevated LV filling pressures (Vp<45 cm/s for subjects older than 30 years and Vp<55 cm/s for subjects younger than 30 years old).
