Feasibility of One-Beat Real-Time Full-Volume Three-Dimensional Echocardiography for Assessing Left Ventricular Volumes and Deformation Parameters

Abstract-This study evaluates the consistency between the bicycle torque of the proposed system, and a Schoberer Rad Messtechnik (SRM) system. The torque was measured while a trainer was cycling indoors, and the measured values were compared with those of the SRM system. A Bland-Altman statistical analysis indicated that the measured values agreed with the SRM within 95%. The mean absolute percentage error and root mean square error between the measurements of the proposed system and the SRM system were 8.25%, and 1.86, respectively. The results show that the bicycle torque can be measured accurately and transmitted using ZigBee wireless protocol.

“…After initialization, the software automatically identifies the heart chambers, and determines the end‐diastolic (ED) and end‐systolic (ES) frames using motion analysis. The software then automatically builds ED and ES 3D casts of LA and LV cavities, from which LV and LA volumes are derived directly without geometric assumptions . (Figure ).…”

Purpose To evaluate the accuracy and reproducibility of a new fully automated fast three‐dimensional (3D) transthoracic echocardiography (TTE) software for the simultaneous assessment of left atrial (LA) volumes and LA ejection fraction (EF), left ventricular (LV) volumes, LV mass, and LVEF, and to compare the results obtained with a cardiac magnetic resonance (CMR) reference. Methods We included retrospectively 56 patients (46 men; mean age 63 ± 13 years) in sinus rhythm who had had comprehensive 3D TTE and CMR examinations within 24 hours. Results Despite a slight underestimation of LV and LA volumes, LVEF and LAEF were similar using CMR or 3DTTE (58% ± 16% vs 58% ± 12%; P = .65 and 45% ± 14% vs 46% ± 15%; P = .38, respectively) in the total population. Despite significant correlation between TTE and CMR measurements (r = 0.78; P < .001), 3D TTE underestimated LV mass (bias = −27 ± 35 g). Conclusion 3D TTE using a new‐generation fully automated software is a fast and reproducible imaging modality for simultaneous extensive quantification of left heart chambers size and function in routine practice. Potential underestimation of LA volume and LV mass, and of LVEF in patients with LVEF <50%, should be taken into consideration.

“…The fact is that both accuracy and reproducibility are improved by automation, and reproducibility is considerably worse when experts perform tasks manually, whether in a fully manual manner or by making subtle ''adjustments'' to the automation. [10][11][12] This is not to argue that automation is infallible and that it should be implemented without the ability to override what is obviously incorrect. However, we would note that if automation works in excess of 90% of the time, it will improve work flow significantly and encourage wider use.…”
