Coronary Reaccess After Modified Chimney Stenting in a Self-Expanding Transcatheter Valve-in-Valve

Abstract

We demonstrate a modified technique of heterotopic chimney stenting for coronary obstruction during valve-in-valve transcatheter aortic valve replacement With successful end-on cannulation via the stent ostium. Our technique was reproducible on the bench with successful reaccess and without any interaction between the deployed coronary stent and the prosthetic leaflets. (Level of Difficulty: Advanced.)
