Table 5 Doppler indices based on DTI of the lateral mitral ring and colour M-mode propagation velocity obtained in protocol B, according to the level of invasive PAOP measured during RHC

From: Echocardiographic assessment of pulmonary artery occlusion pressure in ventilated patients: a transoesophageal study

  PAOP ≤ 18 mmHg (n = 24) PAOP > 18 mmHg (n = 8) p Value
Vp (cm/s) 45 ± 10 35 ± 8 0.05
E' lateral (cm/s) 12.9 ± 3.9 9.2 ± 1.3 0.01
E/Vp 1.7 ± 0.6 2.7 ± 0.5 0.0006
E/E' lateral 5.9 ± 2.2 10.6 ± 3.3 0.0002
  1. Abbreviations: DTI, Doppler tissue imaging; PAOP, pulmonary artery occlusion pressure; RHC, right heart catheterisation; Vp, propagation velocity of early diastolic blood flow within the LV measured using colour M-mode.
