Transcatheter Aortic Valve Implantation Is Feasible and Safe in Nonagenarians

To the Editor: Aortic valve stenosis (AS) is a common disease, with greater prevalence with age. It is associated with poor quality of life and high morbidity and mortality. One-third of individuals with symptomatic severe AS evaluated for surgical aortic valve replacement (AVR) are denied surgery, and advanced age is the most common reason for decline. Over the past decade, transcatheter aortic valve implantation (TAVI) has been established as an alternative method to AVR in individuals with severe AS who are denied surgical AVR because they are at high risk. The shortand medium-term results of TAVI in these individuals are comparable with those of surgical AVR, but the results of TAVI in very elderly adults are largely unknown.
