Mechanical complications such as anchoring strut fracture are rare but may have implications for long-term valve durability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case summary<\/jats:title>\n                    <jats:p>A 64-year-old man with severe symptomatic native AR underwent transapical TAVR using a 29-mm self-expanding J-Valve system. Routine echocardiography and gated CT on postoperative day 7 identified an isolated fracture of the right coronary sinus anchoring strut without migration, leaflet dysfunction, or haemodynamic compromise. No balloon post-dilatation was performed. Serial multimodal imaging over nearly 3 years demonstrated persistent structural stability, preserved valve function, and marked left-ventricular reverse remodelling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This case provides long-term multimodal imaging follow-up of isolated anchoring strut fracture after TAVR for native AR. Early fracture detection and absence of calcification support a deployment-related stress mechanism rather than late cyclic fatigue. Although this favourable evolution suggests that isolated fracture does not necessarily result in immediate structural valve dysfunction, prognostic conclusions cannot be generalized. Careful, individualized imaging surveillance remains essential.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytag448","type":"journal-article","created":{"date-parts":[[2026,6,16]],"date-time":"2026-06-16T12:39:48Z","timestamp":1781613588000},"source":"Crossref","is-referenced-by-count":0,"title":["Stable valve function after post-transapical TAVR with anchoring strut fracture: a 3-year multimodal imaging follow-up case report"],"prefix":"10.1093","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0555-2136","authenticated-orcid":false,"given":"Weili","family":"Liu","sequence":"first","affiliation":[{"name":"Interventional Operation Room, Affiliated Hospital of Qingdao University , No. 16 Jiangsu Road, Qingdao 266003 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4816-6099","authenticated-orcid":false,"given":"Dacheng","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, PET Center, West Coast Campus, Affiliated Hospital of Qingdao University , No. 1677 Wutaishan Road, Huangdao District, Qingdao 266555 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Zhang","sequence":"additional","affiliation":[{"name":"Interventional Operation Room, Affiliated Hospital of Qingdao University , No. 16 Jiangsu Road, Qingdao 266003 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumin","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Affiliated Hospital of Qingdao University , No. 16 Jiangsu Road, Qingdao 266003 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1346-6291","authenticated-orcid":false,"given":"Lei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Affiliated Hospital of Qingdao University , No. 16 Jiangsu Road, Qingdao 266003 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,6,20]]},"reference":[{"key":"2026062616112781500_ytag448-B1","doi-asserted-by":"crossref","first-page":"1695","DOI":"10.1056\/NEJMoa1814052","article-title":"Transcatheter aortic-valve replacement with a balloon-expandable valve in low-risk patients","volume":"380","author":"Mack","year":"2019","journal-title":"N Engl J Med"},{"key":"2026062616112781500_ytag448-B2","doi-asserted-by":"crossref","first-page":"561","DOI":"10.1093\/eurheartj\/ehab395","article-title":"2021 ESC\/EACTS guidelines for the management of valvular heart disease","volume":"43","author":"Vahanian","year":"2022","journal-title":"Eur Heart J"},{"key":"2026062616112781500_ytag448-B3","doi-asserted-by":"crossref","first-page":"2752","DOI":"10.1016\/j.jacc.2017.10.006","article-title":"Outcomes after transcatheter aortic valve replacement in patients with severe aortic regurgitation","volume":"70","author":"Yoon","year":"2017","journal-title":"J Am Coll Cardiol"},{"key":"2026062616112781500_ytag448-B4","doi-asserted-by":"crossref","first-page":"1830","DOI":"10.1016\/j.jacc.2020.08.049","article-title":"Structural deterioration of transcatheter versus surgical aortic valve bioprostheses in the PARTNER 2 trial","volume":"76","author":"Pibarot","year":"2020","journal-title":"J Am Coll Cardiol"},{"key":"2026062616112781500_ytag448-B5","doi-asserted-by":"crossref","first-page":"2062","DOI":"10.1016\/j.jcin.2025.05.005","article-title":"Acute fracture of a self-expanding transcatheter aortic valve after postdilatation resulting in structural valve deterioration","volume":"18","author":"Maznyczka","year":"2025","journal-title":"JACC Cardiovasc Interv"},{"key":"2026062616112781500_ytag448-B6","doi-asserted-by":"crossref","first-page":"e007349","DOI":"10.1161\/CIRCINTERVENTIONS.118.007349","article-title":"Early and late leaflet thrombosis after transcatheter aortic valve replacement","volume":"12","author":"Yanagisawa","year":"2019","journal-title":"Circ Cardiovasc Interv"},{"key":"2026062616112781500_ytag448-B7","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jcmg.2018.12.003","article-title":"Computed tomography imaging in the context of transcatheter aortic valve implantation (TAVI)\/TAVR: an expert consensus document","volume":"12","author":"Blanke","year":"2019","journal-title":"JACC Cardiovasc Imaging"}],"container-title":["European Heart Journal -
