Small aortic annulus
Webb4 feb. 2024 · Should the mitral annulus be too small to fit a mitral prosthesis, an reversely implanted aortic valve prosthesis needs to be considered . However, an enlargement of the mitral annulus might be a superior technique for these cases as to minimise transvalvular gradient as well as improved valve durability in biological prosthesis of larger sizes [ 56 , … 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.
