TI  - New digital measurement methods for left ventricular volume using real-time 
      three-dimensional echocardiography: comparison with electromagnetic flow method 
      and magnetic resonance imaging.
PG  - 96-104
AB  - AIM: The aim of this study was to investigate the feasibility and accuracy of 
      using symmetrically rotated apical long axis planes for the determination of left 
      ventricular (LV) volumes with real-time three-dimensional echocardiography (3DE). 
      METHODS AND RESULTS: Real-time 3DE was performed in six sheep during 24 
      haemodynamic conditions with electromagnetic flow measurements (EM), and in 29 
      patients with magnetic resonance imaging measurements (MRI). LV volumes were 
      calculated by Simpson's rule with five 3DE methods (i.e. apical biplane, 
      four-plane, six-plane, nine-plane (in which the angle between each long axis 
      plane was 90 degrees, 45 degrees, 30 degrees or 20 degrees, respectively) and 
      standard short axis views (SAX)). Real-time 3DE correlated well with EM for LV 
      stroke volumes in animals (r=0.68-0.95) and with MRI for absolute volumes in 
      patients (r-values=0.93-0.98). However, agreement between MRI and apical 
      nine-plane, six-plane, and SAX methods in patients was better than those with 
      apical four-plane and bi-plane methods (mean difference = -15, -18, -13, vs. -31 
      and -48 ml for end-diastolic volume, respectively, P<0.05). CONCLUSION: Apically 
      rotated measurement methods of real-time 3DE correlated well with reference 
      standards for calculating LV volumes. Balancing accuracy and required time for 
      these LV volume measurements, the apical six-plane method is recommended for 
      clinical use.
