AB  - OBJECTIVE: This study aims to explore the feasibility of HeartModel (A.I.) (HM) 
      three-dimensional echocardiography (3DE) to assess left ventricular function and 
      discover suitable border parameter settings. METHODS: A total of 113 patients 
      that underwent echocardiography in our hospital were eligible for inclusion. The 
      HM 3DE (HM method) and conventional 3DE (3D method) were used to analyze 
      echocardiography images. The HM was set to different border settings 
      (end-diastolic [ED] and end-systolic [ES] settings) to assess different left 
      ventricular systolic function parameters including left ventricular end diastolic 
      volume (LVEDV), left ventricular end systolic volume (LVESV), and left 
      ventricular ejection fraction (LVEF), and left ventricular diastolic function 
      parameters including maximal left atrium volume (LAV(MAX)). All of these 
      parameters were evaluated using the HM method and then compared with the 3D 
      method. RESULTS: The differences in LVEDV, LVESV, and LVEF measured with 
      different HM border settings were statistically significant (P<0.05) and were 
      strongly correlated with the 3D method. For LVEF, the reading using the HM method 
      with ED and ES = 70 and 30 showed the best agreement with the 3D method, and the 
      difference in the readings was not statistically significant (P > 0.05). For 
      LVEDV and LVESV, the reading using the HM method with ED and ES = 40 and 20 
      showed the best agreement with the 3D method, but the difference in the readings 
      was statistically significant (P < 0.05). The measurements taken using the HM 
      method were more reproducible than those taken using the 3D method (P<0.05). The 
      measurement time when using the HM method was significantly less than the 3D 
      method (P<0.05). In terms of LAV(MAX), the correlation between the HM and 3D 
      methods was strong, but the requirements for agreement were not satisfied. 
      CONCLUSION: Evaluation of the left ventricular function using HM 3DE is feasible, 
      saves time, and is reproducible. To assess the left ventricular function, the 
      border parameter setting of ED and ES = 70 and 30 provided the best fit for the 
      Chinese population.
