The impact of frailty on mortality after transcatheter aortic valve replacement.

Frailty is a notably common problem in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) evaluation. Studies have demonstrated significant associations between frailty and worse outcomes in patients undergoing TAVR including higher risks of disability and mortality and admissions to long-term care facility. While there are multiple methods to identify and measure frailty, there is a critical need for a precise definition of frailty and its standardized assessment protocol based on well-established tests covering all aspects of the frailty, as a syndrome. Incorporation of the available frailty evaluation into pre-operative risk assessments chances of morbidity or mortality following surgery can help enhancing performance and improve shared decision-making between physicians and their patients. In this review, we present the perspectives of the impact of frailty on mortality in patients undergoing TAVR.
