Role of computed tomography as a preprocedural evaluation tool in transcatheter aortic valve replacement

Abstract

Abstract Transcatheter aortic valve replacement (TAVR) is increasingly becoming the preferred innovative approach for high-risk aortic stenosis patients. However, before undergoing TAVR, it is crucial to undergo a noninvasive and accurate assessment for proper valve sizing and planning the access route. Computed tomography (CT) imaging plays a vital role in evaluating patients scheduled for transcatheter aortic valve implantation (TAVR). It offers comprehensive information about the aortic valve complex anatomy and the preferred access route, ensuring effective patient selection, and guiding the selection of the appropriate prosthesis. In addition, CT imaging aids in determining the fluoroscopic projection angle, leading to reduced procedural time and optimized use of contrast and radiation exposure.
