TLDR
The new automatic 3D-TOE software allows modelling and quantifying the aortic root from 3D -TOE data with high reproducibility and there is good correlation between the automated measurements and other 3D validated techniques.Abstract:
Aims A specialized three-dimensional transoesophageal echocardiography (3D-TOE) reconstruction tool has recently been introduced; the system automatically configures a geometric model of the aortic root from the images obtained by 3D-TOE and performs quantitative analysis of these structures. The aim of this study was to compare the measurements of the aortic annulus (AA) obtained by the new model to that obtained by 3D-TOE and multidetector computed tomography (MDCT) in candidates to transcatheter aortic valve implantation (TAVI) and to assess the reproducibility of this new method.
Methods and results We included 31 patients who underwent TAVI. The AA diameters and area were evaluated by the manual 3D-TOE method and by the automatic software. We showed an excellent correlation between the measurements obtained by both methods: intra-class correlation coefficient (ICC): 0.731 (0.508–0.862), r : 0.742 for AA diameter and ICC: 0.723 (0.662–0.923), r : 0.723 for the AA area, with no significant differences regardless of the method used. The interobserver variability was superior for the automatic measurements than for the manual ones. In a subgroup of 10 patients, we also found an excellent correlation between the automatic measurements and those obtained by MDCT, ICC: 0.941 (0.761–0.985), r : 0.901 for AA diameter and ICC: 0.853 (0.409–0.964), r : 0.744 for the AA area.
Conclusion The new automatic 3D-TOE software allows modelling and quantifying the aortic root from 3D-TOE data with high reproducibility. There is good correlation between the automated measurements and other 3D validated techniques. Our results support its use in clinical practice as an alternative to MDCT previous to TAVI.read more

TL;DR: For pre‐TAVR planning, 3D TEE is comparable to MDCT and in patients with renal dysfunction, 3d TEE may be potentially advantageous for TAVR measurements because of the lack of contrast exposure.

TL;DR: The proposed approach mitigates the variability associated with the manual quantification while significantly reducing the required analysis time (12 s versus 5 to 10 min), which shows its appeal for automatic dimensioning of the AV morphology in 3-D-TEE for the planning of transcatheter AV implantation.

TL;DR: In patients with severe aortic stenosis who were not suitable candidates for surgery, TAVI, as compared with standard therapy, significantly reduced the rates of death from any cause, the composite end point of deathFrom any cause or repeat hospitalization, and cardiac symptoms, despite the higher incidence of major strokes and major vascular events.
