Poor long-term survival in patients with moderate aortic stenosis

Keywords: aortic stenosis; severity; mortality

The association between severe aortic stenosis (AS) and poor survival is well known. While some studies have indicated that this association also applies to less severe AS, the research has been limited by sample size and length of follow-up. Overall, the progression and management of AS is poorly characterised.

This summary presents key data from a retrospective cohort study assessing the prognostic impact of increasing AS severity. Strange et al. assessed data from 241,303 patients obtained from the National Echocardiographic Database of Australia registry. Short- and long-term mortality rates (1 and 5 years) were examined according to AS severity.
