Coronary Access After Chimney Stenting During Valve-in-Valve TAVI for Failed Surgical Bioprosthetic Valves: Impact of Valve Design

Published:February 18, 2022DOI:https://doi.org/10.1016/j.cjca.2022.02.015
      We developed advanced computed tomography–based 3-dimensional (3D) models to demonstrate how transcatheter valve design may affect future coronary access in aortic valve implantation patients. Transcatheter aortic valve-in-valve implantation (ViV-TAVI) for failed surgical bioprosthetic valves is associated with an increased risk of coronary artery obstruction.
