Aortic stenosis (AS) has become an increasingly prevalent condition in ageing Western populations. Symptomatic AS is associated with significant morbidity, high hospitalisation rates and reduction in quality of life and life-expectancy. A large number of patients with severe AS are not currently receiving proper treatment, with subsequent increased mortality. While surgical aortic valve replacement continues to be an effective treatment for these patients, transcatheter aortic valve implantation is a new alternative for those at high risk from surgery. Overall, valve replacement and implantation procedures have a significant impact on prognosis and quality of life in AS patients. Referring a patient to a centre that has a multidisciplinary heart team will ensure that all treatment options are fully explored and the best clinical outcomes are reached.
