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. Webb12 feb. 2024 · The aortic root is considered small when the diameter of the aortic valve annulus measures 21 mm or less in adult patients. An important consideration for the surgeon is to ensure that the patient receives a prosthetic valve that is adequately sized to achieve low transvalvular gradients.

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.
