Webb14 juli 2024 · Aortic stenosis is the most common valve disease requiring surgery or percutaneous treatment. Since the first-in-man implantation in 2002 we have witnessed incredible progress in transcatheter aortic valve implantation (TAVI). In this article, we review the technical aspects of TAVI development with a look at the future. Durability, … Webb1 jan. 2016 · Hypoplasia of the aortic valve annulus, diffuse obstructive of the LVOT, and the lack of growth after prosthetic valve insertion have led to the design of a number of procedures aiming to enlarge the aortic root. 17 The goals of any procedure that aims to restore adequate function of a pathologically small aortic root must include the relief of …
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 , … Webb1 mars 2024 · The mean Society of Thoracic Surgeons score was 6.22±6.08, with 52.5% patients with small aortic annulus (<23mm), 33.2% patients with medium aortic annulus (23-26mm) and 14.3% patients with large ...
WebbPatients with aortic stenosis (AS) and small aortic annulus (SAA) who undergo surgical aortic valve replacement (SAVR) are more likely to receive smaller prostheses, predisposing them to prosthesis patient-mismatch (PPM). Since the Ozaki Procedure (aortic valve neocuspidization – AVNeo) has proved promising, we aimed to assess its … 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.
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.
