TI  - Mitral annulus displacement measured by tissue-tracking method with 
      Doppler-tissue images is a useful marker of the severity of heart failure.
PG  - 159-66
AB  - OBJECTIVES: This study investigated whether the measurement of mitral annulus 
      displacement by the tissue-tracking method with Doppler-tissue images can provide 
      more accurate information on the severity of heart failure compared to 
      conventional methods, such as left ventricular ejection fraction (LVEF). 
      BACKGROUND: Impaired left ventricular function is an important predictor of poor 
      prognosis. Although LVEF has been used to assess left ventricular function, such 
      indicators do not necessarily correlate well to clinical variables such as New 
      York Heart Association (NYHA) functional class or plasma brain natriuretic 
      peptide (BNP) concentration. METHODS: In 90 subjects with or without various 
      heart diseases, mitral annulus displacement was measured by the tissue-tracking 
      method with Doppler-tissue images and the correlations evaluated with NYHA 
      functional class, plasma BNP concentration, left ventricular mass index and Tei 
      index. RESULTS: Mitral annulus displacement by the tissue-tracking method with 
      Doppler-tissue images was well correlated with NYHA functional class and plasma 
      BNP concentration. LVEF was also correlated with these clinical variables, but 
      significantly more weakly. Furthermore, mitral annulus displacement by the 
      tissue-tracking method with Doppler-tissue images was correlated with left 
      ventricular mass index and Tei index, which indicate left ventricular systolic 
      and diastolic function. CONCLUSIONS: The present study suggests that mitral 
      annulus displacement measured by our technique is a useful and reliable method 
      for assessing the severity of heart failure.
