Webb9 feb. 2016 · In patients referred for TAVI, measurements of the aortic annulus using TTE, TEE, and MSCT were close but not identical. The method used has important potential clinical implications on TAVI strategy. The annulus size is in general 1 mm smaller by TTE than by TEE, and the TEE measurement is 1 to 1.5 mm smaller than MSCT measurements. Webb23 aug. 2024 · Implantation of a small aortic valve sometimes leads to high residual gradients, despite a normally functioning prosthesis. Patients with a small aortic annulus, especially those with a large body surface area, are at higher risk of prosthesis-patient mismatch, which is associated with worse clinical outcomes and decreased survival.
