Of these, 66% were men and 64% were aged &gt;70 years. Absolute rates of AVR increased from 3631 to 7277 with a significant 22% age\u2010adjusted rise seen (1.9% increase per year (+0.26 per 100\u2009000 per year; 95% confidence interval 0.19\u20130.34); <jats:italic>P<\/jats:italic> &lt;\u20090.001).

A total of 2683 transcatheter aortic valve implantation (TAVI) procedures was performed in 2019, representing a 52% annual increase from 2014.

Despite international guideline recommendations, fewer mechanical AVR are being used in younger cohorts. The uptake in TAVI rates might reflect evidence that suggests it is a safe alternative, at least in the medium term. BAV has also seen a resurgence during this time period.<\/jats:p><\/jats:sec>","DOI":"10.1111\/imj.15624","type":"journal-article","created":{"date-parts":[[2021,11,15]],"date-time":"2021-11-15T14:11:38Z","timestamp":1636985498000},"page":"525-530","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Aortic valve replacement rates in Australia from 2004 to 2019"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5533-3919","authenticated-orcid":false,"given":"Paul","family":"Bamford","sequence":"first","affiliation":[{"name":"Cardiology Department John Hunter Hospital  Newcastle New South Wales Australia"},{"name":"School of Medicine and Public Health University of Newcastle  Newcastle New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Said","sequence":"additional","affiliation":[{"name":"Cardiology Department Gosford Hospital  Gosford New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed S.","family":"Al\u2010Omary","sequence":"additional","affiliation":[{"name":"Cardiology Department John Hunter Hospital  Newcastle New South Wales Australia"},{"name":"School of Medicine and Public Health University of Newcastle  Newcastle New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rohan","family":"Bhagwandeen","sequence":"additional","affiliation":[{"name":"Cardiology Department John Hunter Hospital  Newcastle New South Wales Australia"},{"name":"School of Medicine and Public Health University of Newcastle  Newcastle New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Boyle","sequence":"additional","affiliation":[{"name":"Cardiology Department John Hunter Hospital  Newcastle New South Wales Australia"},{"name":"School of Medicine and Public Health University of Newcastle  Newcastle New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,8,20]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.4065\/mcp.2009.0706"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2261-14-134"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehx391"},{"key":"e_1_2_6_5_1","unstructured":"Australian Government: Department of Health \u2013 Medical Services Advisory Committee1603 \u2013 Transcatheter aortic valve implantation (TAVI) via transfemoral delivery using the SAPIEN 3 balloon\u2010expandable valve (BEV) system for patients at intermediate risk for surgery.
