Performance of new automated transthoracic three-dimensional echocardiographic software for left ventricular volumes and function assessment in routine clinical practice: Comparison with 3 Tesla cardiac magnetic resonance

Abstract

3D TTE using new-generation fully automated software is a feasible, fast, reproducible and accurate imaging modality for LV volumetric quantification in routine practice. Optimization of border detection settings may increase agreement with CMR for EDV assessment in dilated ventricles.

Performance of a new fully automated transthoracic three‐dimensional echocardiographic software for quantification of left cardiac chamber size and function: Comparison with 3 Tesla cardiac magnetic resonance

“…In the remaining patients, 3D quantification was either unreliable because of insufficient image quality or unavailable because of failure of automated software analysis. Another study recently reported similar findings as 14% of the patients were excluded because of insufficient echogenicity . In patients with atrial fibrillation, recent data suggest that 3DTTE automated software may also provide reliable averaged values of LV variables during multiple consecutive beats …”

“…The software used in our study may overcome such drawbacks, as it offers the possibility to define larger default border detection settings, within the myocardium. Previous study showed that automated border detection standard settings correlate well with CMR in the general population. Nevertheless, more accurate assessment of LV volumes seems to require larger 3D border settings in patients with a dilated LV and altered LVEF …”

“…Reproducibility of 3DTTE using HeartModel A.I. is known to be excellent with low inter‐ and intra‐observer variability . This new automated application uses knowledge‐based identification of LV chambers followed by patient‐specific adaptation .…”

“…Nevertheless, time‐consuming workflow and the need for 3D expertise have limited the integration of 3D quantification into clinical practice . Recently, initial validation of fully automated 3D TTE software, which does not require any input once the dataset has loaded, has shown good accuracy and reproducibility, with promising time saving potential . Recent upgrade of the software provides more extensive quantification of left heart chambers with simultaneous automatic measurements of LV and LA volumes and function along with LV mass.…”

Automated, machine learning‐based, 3D echocardiographic quantification of left ventricular mass

“…A previous version of this algorithm was validated for the assessment of LV size and function [19][20][21][22][23] in patients with good quality images, and most recently in unselected patients.
