The UK Transcatheter Aortic Valve Implantation (TAVI) registry has collected data about every TAVI procedure performed in the UK. The latest data are from 2016 when 3250 procedures (49.5 pmp) were performed. There has been no change in the mean age of patients but there has been a shift to lower risk with fall in mean Logistic Euroscore since 2012. The switch from general anaesthetic to conscious sedation has been rapid, and propensity-adjusted analysis has not shown a difference in outcomes. In-hospital mortality has fallen to 1.8% in 2016, and relative survival analysis has shown outcome the same as the matched general population to 3 years. The UK TAVI registry has provided valuable benchmarks, and a risk adjustment model that includes frailty measures has been successfully developed and is available online.
