Small aortic annulus
Webb1 nov. 2024 · Background: Small aortic annulus during aortic valve replacement can lead to implanting a smaller sized valve compared to the body surface area thereby causing … WebbAnatomically, the aortic annulus (AA) is a complex 3-dimensional (3D) crown-shape structure that is part of the fibrous skeleton of the heart. From a surgical stand point, the AA is generally located at the anatomic ventriculoaortic junction onto which a prosthetic valve can be sewn.

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 … WebbAs women tend to be smaller in body size, they also show smaller aortic annulus (Supplemental Table S5). Nevertheless, the heart team discusses anatomical measurements of the aortic annulus in order to choose the best fitting valve. Therefore, we calculated the oversizing factors in respect to patients’ sex.
