Nearly one-quarter, 24%, with indications for intervention were planned for conservative management while 36% had a decision for intervention apparently without a recognised indication. Overall, 26% received apparently inappropriate treatment decisions which is similar to the 30% shown by the first EuroHeart survey.1

The IMPULSE registry, funded by Edwards Lifesciences, is a prospective international multicentre registry-based cohort study evaluating the care of patients with severe AS3 in 23 centres in 9 European countries.
