Use of the reported Edmonton frail scale in the assessment of patients for transcatheter aortic valve replacement： a possible selection tool in very high-risk patients？

Transcatheter aortic valve replacement （TAVR） has revolutionised the treatment of patients with aortic stenosis （AS） over the last 15 years.TAVR is a well-established procedure for the treatment of patients considered high risk for open surgery. Results from the PARTNER （Placement of AoRTic traNscathetER） trial showed that inoperable patients randomly assigned to TAVR, had a 20% reduction in all-cause mortality, as well as hospitalisation, at one year compared to best medical management.
