چکیده انگلیسی

BackgroundTraditional 3-dimensional echocardiography (3DE) with volumetric scanning technique requires several heart cycles for full-volume acquisition and complicated manual contouring of left ventricular (LV) endocardium. The new real-time 3DE (RT3DE) system allows acquisition of an instantaneous full-volume dataset in a single heart cycle and automated measurement of LV volume by the algorithm software. However, it has not been evaluated adequately whether automated measurement by RT3DE has better agreement with cardiac magnetic resonance imaging (CMR) than 2-dimensional echocardiography (2DE) with CMR.PurposeThis study aimed to evaluate the accuracy of automated measurement of LV volume using RT3DE compared with 2DE and CMR.Methods and resultsForty-four consecutive patients who underwent RT3DE, 2DE, and CMR were evaluated in this study. The feasibility of automated measurement by RT3DE was 93.2% and the mean operation time was 6 min. LV volume and ejection fraction (EF) from semi-automated measurement [end-diastolic volume: r = 0.96, limits of agreement (LOA) −30.5 to 39.3 ml; end-systolic volume: r = 0.97, LOA −22.6 to 32.7 ml; EF: r = 0.90, LOA −16.1 to 14.2%, respectively] had better agreement with CMR than those from 2DE (r = 0.87, LOA −50.5 to 72.2 ml; r = 0.93, LOA −34.1 to 65.2 ml; r = 0.89, LOA −20.9 to 10.0%, respectively).ConclusionSemi-automated measurement by RT3DE has better agreement with CMR than 2DE in LV volume and EF. In addition, it is simple to operate and acceptable in feasibility for the clinical setting although there may be room for further learning required to incorporate small hypertrophic LV into the automated algorithm software.
