title: The Cor-Knot device may serve as an ideal radiopaque marker of the annular plane for future valve-in-valve implantation.
abstract: A 55-year-old man underwent aortic root and ascending aortic replacement with a 27-mm Freestyle porcine neoroot with reimplantation of the coronary ostia as well as ascending aortic replacement with a 28-mm straight Dacron graft. A knot-tying device consisting of radiopaque Titan clips (Cor-Knot device, LSI Solutions, Inc, Victor, NY) for anchoring the porcine neoroot was used.
