An Adjustable Aortic Annuloplasty Ring for Symmetric Aortic Annulus Reduction
Stanford researchers in the Woo Lab have designed an implantable prosthetic for patients with aortic valve dysfunction, particularly for use in valve-sparing aortic root replacement procedures. The device, made from a flexible biocompatible material, is positioned externally to the aortic valve and includes a tightening mechanism, such as an embedded suture. This mechanism allows for the symmetric reduction of the prosthetic ring's diameter by narrowing the distances between the valve's commissures and nadirs.
