Valve-in-Valve Transcatheter Valve Implantation in the Nonaortic Position [PDF]
Journal of Cardiac Surgery, 2016 Transcatheter valve-in-valve (VIV) procedures are an alternative to standard surgical valve replacement in high risk patients.Cases in which a commercially approved transcatheter aortic valve replacement (TAVR) device was used for a nonaortic VIV procedure between November 2013 and September 2015 are reviewed.
