However, few clinical studies have concentrated on the application of TAVR in elderly AS patients. This study aimed to explore the efficacy and safety of TAVR in elderly patients with AS.Methods: Clinical and imaging data of 143 AS patients undergoing Transcatheter aortic valve replacement were retrospectively analyzed. These patients were divided into non-elderly group (&lt; 65 years old) and elderly group (65 years old), and the baseline characteristics and clinical outcomes were compared between the two groups.Results: The baseline characteristics showed no significant difference between the two groups. After surgery, echocardiography revealed that the forward flow velocity of aortic valve was higher in the non-elderly group than that in the elderly group (234.2 49.8 cm\/s vs. 209.957.7 cm\/s, P=0.022), while there was no significant difference in other indicators. The operation time (197.463.5 min vs. 194.267.8 min, P=0.811), length of hospital stay (14.07.3 days vs.14.27.6 days, P=0.874), incidence of perioperative complications (2.2% vs. 4.1%, P=1.000), and mortality rate (0.0% vs. 1.0%, P=1.000) sho wed no significant differences between the two groups.Conclusion: Transcatheter aortic valve replacement is an effective and safe therapeutic approach for elderly patients with aortic stenosis.\r\nKeywords: Valvular heart disease, Aortic stenosis; Elderly patients; Transcatheter aortic valve replacement, Echocardiography.<\/jats:p>","DOI":"10.4314\/ahs.v25i1.20","type":"journal-article","created":{"date-parts":[[2025,7,30]],"date-time":"2025-07-30T11:43:38Z","timestamp":1753875818000},"source":"Crossref","is-referenced-by-count":1,"title":["The efficacy and safety of transcatheter aortic valve replacement in elderly patients with aortic stenosis"],"prefix":"10.4314","volume":"25","author":[{"given":"Jinghui","family":"An","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengwu","family":"Shi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huajun","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Su","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2895","published-online":{"date-parts":[[2025,5,9]]},"container-title":["African Health Sciences"],"original-title":[],"link":[{"URL":"https:\/\/www.ajol.info\/index.php\/ahs\/article\/download\/295070\/277648","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.ajol.info\/index.php\/ahs\/article\/download\/295070\/277648","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,7]],"date-time":"2025-11-07T14:06:29Z","timestamp":1762524389000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ajol.info\/index.php\/ahs\/article\/view\/295070"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5,9]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,5,9]]}},"URL":"https:\/\/doi.org\/10.4314\/ahs.v25i1.20","relation":{},"ISSN":["1729-0503","1680-6905"],"issn-type":[{"value":"1729-0503","type":"electronic"},{"value":"1680-6905","type":"print"}],"subject":[],"published":{"date-parts":[[2025,5,9]]}}}
