ABSTRACT
Objective:
To investigate the clinical value of left ventricular function assessment in patients with cardiovascular disease by fully automatic quantified three-dimensional transthoracic echocardiography.Methods:
One hundred and ninety-seven patients with cardiac diseases were examined by three-dimensional transthoracic echocardiography from September 2017 to May 2019. Data from 61 patients with grade 1 echocardiographic image quality were used to determine the default boundary values of endocardial end-diastolic and end-systolic phases. Clinical features were analyzed based on electronic medical records. The accuracy and repeatability of this strategy was evaluated by comparing left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) measured by automated quantitative three-dimensional echocardiography and those measured by conventional manual transthoracic echocardiography, the latter served as gold standard.Results:
The levels of LVEDV, LVESV and LVEF measured by automatic three-dimensional echocardiography were positively correlated with values obtained by manual measurement(r=0.97,0.97, 0.98, 0.97, 0.97, 0.96;P<0.05). The levels of LVEDV and LVESV measured by full-automatic three-dimensional echocardiography were significantly higher than those obtained by manual three-dimensional echocardiography(all P<0.05). The classification and correlation of systolic dysfunction in patients with abnormal ventricular wall motion by automatic three-dimensional echocardiography were significantly improved after manual calibration (κ=0.74, P=0.00) as compared to without manual calibration (κ=0.63, P=0.00). The inter-observer and intra-observer variability of fully automated three-dimensional echocardiography were significantly smaller than manual three-dimensional echocardiography(both P<0.05).Conclusion:
Fully automatic quantified three-dimensional transthoracic echocardiography possesses excellent accuracy and repeatability in measuring left ventricular volume and function, and it is feasible for clinical application.Key words
