Key result
Automated 3D TEE and MDCT led to the same TAVI prosthesis size selection in 88% of patients overall, with 95% agreement in those with low aortic valve calcium burden.
Why the study?
Does automated 3D TEE agree with MDCT for aortic annulus sizing and TAVI prosthesis selection in patients with severe aortic stenosis?

Supports automated 3D TEE for TAVI sizing in low AVC burden; hypothesis-generating and requires prospective validation before practice change.

Does automated 3D TEE agree with MDCT for aortic annulus sizing and TAVI prosthesis selection in patients with severe aortic stenosis?
Automated 3D TEE provides accurate aortic annulus sizing with excellent agreement with MDCT for TAVI prosthesis selection, especially in patients with low aortic valve calcium burden.
Podlesnikar et al. (2017) conducted an observational in Severe aortic stenosis (n=83). Automated 3-dimensional transesophageal echocardiography (3D TEE) vs. Multidetector row computed tomography (MDCT) was evaluated on Agreement on TAVI prosthesis size selection. Automated 3D TEE and MDCT led to the same TAVI prosthesis size selection in 88% of patients overall, with 95% agreement in those with low aortic valve calcium burden.
