BACKGROUND Several surgical and percutaneous treatments are available for patients with aortic valve disease. AIM Our aim is to establish whether trends in aortic valve replacements (AVR) in Australia reflect recent evidence. METHODS Using Australian Institute of Health and Welfare data, this study counted all AVR and balloon aortic valvuloplasty (BAV) procedures conducted in all Australian hospitals from 2004 to 2019. Linear regression analysis was performed to determine whether age-adjusted rates had changed over the study period. RESULTS There were 80,883 AVRs performed. 66% were men and 64% were over aged 70. Absolute rates of AVR increased from 3,631 to 7,277 with a significant 22% age-adjusted rise seen (1.9% increase per year (+0.26 per 100,000 per year, 95% CI 0.19 - 0.34); p
