Systems and Methods for Assessing Valve-In-Valve Risks

Abstract

Systems and methods for evaluating a proposed valve-in-valve procedure for a patient in which a replacement transcatheter aortic valve will be deployed within a first bioprosthetic aortic valve. The methods include selecting predetermined benchmark measurements of a valve-in-valve combination. Images of anatomy of the patient are received. Anatomical measurements of the first bioprosthetic valve are obtained from the received images. The predetermined benchmark measurements and the anatomical measurements are reviewed. Based, at least in part, upon the review, risks of a valve-in-valve procedure for the patient are evaluated. The methods of the present disclosure can be used on baseline scans of a patient without a first bioprosthetic valve implanted; under these circumstances, dimensions of the first valve are determined by benchmark measurements. Where methods of the present disclosure are used on post-first implant scans, then the dimensions of the first valve are determined from the post-implant scans.
