title: [Three-dimensional echocardiography in assessment of left ventricular myocardial mass: comparison of the results of one-dimensional, two-dimensional echocardiography and MR tomography].
abstract: OBJECTIVE
  To compare different techniques of calculation of left ventricular myocardial mass (LVMM) by one-, two- and three-dimentional echocardiography (EchoCG) and by MRT.
  
  
  METHODS
  We calculated LVMM by formulas Penn-cub and modified ASE in one-, two- and three-dimentional EchoCG regimes and MRT; evaluated structural-geometrical characteristics of the left ventricle at various stages of hypertension in 53 hypertensive patients (42 males and 11 females).
  
  
  RESULTS
  Mean LVMM values calculated according to two formulas in one-dimentional regime did not differ significantly but were higher than in two- and three-dimentional regimes. LVMM value according to three-dimentional EchoCG was closer to the results of the summation estimation in MRT.
  
  
  CONCLUSIONS
  Conventional EchoCG methods of LVMM calculation in M-regime (Penn-cub, ASE) overestimate the results. Most compatible with three-dimentional EchoCG results are those of EchoCG in two-dimentional regime (area-length).
