Due to the ageing and increasingly complex nature of patients with aortic stenosis, frailty and functional assessment has become a high-priority theme within patient management. Frailty is a term widely used to describe a multidimensional syndrome of loss of reserves (energy, physical ability, cognition, health) that gives rise to vulnerability. Several publications deal with the impact of frailty on mortality and morbidity in the elderly population. Functional status is evaluated by the ability to undertake Activities of Daily Living (ADL) and it has been demonstrated that frailty and the onset of dependence in ADL are strongly associated.
