1 Introduction Aortic stenosis (AS) is the most common heart valve disease in the developed world, with the prevalence increasing alongside the ageing population (Chatterjee et al. 2023; Joseph et al. 2017). In higher-income countries, AS is the third leading cause of cardiovascular death and in 2019 there were an estimated 9.4 million cases of calcific aortic valve disease globally, and 102,700 associated deaths (Roth et al. 2020; Yadgir et al. 2020).

1 INTRODUCTION Definitions and constructs of personhood in healthcare are contextual, and often depend on culture, beliefs and the medical conditions that affect a person, including impacts on their rationality, self-determination and capacity to interact with their social world (Garthoff, 2019; Penner & Hull, 2008; Scharmer, 2018; Walker & Lovat, 2015).

4. Discussion The purpose of this exploratory study was to examine the acceptability and feasibility of using wearable trackers to measure incidental PA in older, frail adults with severe AS before and after AVR. In our study, before AVR, these older AS participants were symptomatic and managing multiple comorbidities.
