TI  - [Evaluation of the clinical suitability of automated left ventricle's fraction 
      and volume measurements in 3-dimensional echocardiography compared to values 
      obtained in magnetic resonance imaging (pilot study)].
PG  - 154-157
AB  - Recently a lot of authors have been trying to determine the usefulness of 
      3-dimensional echocardiography (TTE 3D) in evaluation of ejection fraction and 
      left ventricular volume, but few attempt to compare it to the current gold 
      standard of cardiac magnetic resonance (CMR). 3D imaging technics allows to avoid 
      errors caused by geometry of the heart chambers and foreshortened views. American 
      Echocardiographic Guidelines recommend the use of 3-dimensional echocardiography 
      in daily clinical practice. AIM: The aim of the study was to establish clinical 
      usefulness of automated 3D TTE software to calculate left ventricle ejection 
      fraction (LVEF), left ventricle end diastolic volume (LVEDV) and left ventricle 
      end systolic volume (LVESV), and to compare those measurements calculated in CMR 
      and in 3D TTE. MATERIALS AND METHODS: The aim of the study was to establish 
      clinical usefulness of automated 3D TTE software to calculate left ventricle 
      ejection fraction (LVEF), left ventricle end diastolic volume (LVEDV) and left 
      ventricle end systolic volume (LVESV), and to compare those measurements 
      calculated in CMR and in 3D TTE. RESULTS: The mean LVEF in 3D TTE was 65% +/- 
      12%; LVEDV 123 ml +/- 67 ml, LVESV 42 ml +/- 29 ml. The CMR LVEF in the study 
      group was 61% +/- 9%, LVEDV 134 ml +/- 51ml, LVESV 54 ml +/- 33 ml. Wilcoxon rank 
      test showed no difference between medians of the measurements, the correlation 
      coefficient between LVEF in 3D TTE and CMR was R = 0.84 (p = 0.036). LVEF 
      calculated in 3D TTE shows good correlation with LVEF computed in CMR. However 
      good visualization of the endocardium, especially in the apex, is essential. The 
      volume of left ventricle is underestimated in 3D TTE. In previous studies 
      underestimation of LVEDV and LVESV was explained by exclusion of endocardial 
      trabeculae from the left ventricle cavity in automated measurement. CONCLUSIONS: 
      The automated 3D TTE software allows simple, fast and precise evaluation of 
      parameters of the left ventricle - especially LVEF. Automated 3D TTE software 
      gives hope for the inclusion of 3D TTE in routine clinical practice due to its 
      repeatability and easy use of the Heart Model software.
