The presence of a small aortic annulus (SAA) has been associated with a higher incidence of prosthesis\u2013patient mismatch (PPM) when surgical aortic valve replacement (sAVR) is performed. TAVR might be a treatment option offering better hemodynamics with a lower incidence of PPM. When a severe AS with a SAA is treated, TAVR-related risk as the coronary obstruction and the annulus rupture, must be also prevented. We present a case of a TAVR in a very small aortic annulus; to our knowledge, this is the smallest native aortic annulus treated percutaneously in a tricuspid stenotic aortic valve with a Self-Expanding Transcatheter Heart Valve (THV) Acurate Neo 2.<\/jats:p>","DOI":"10.3389\/fcvm.2023.1195486","type":"journal-article","created":{"date-parts":[[2023,9,18]],"date-time":"2023-09-18T05:49:58Z","timestamp":1695016198000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case report: Self-expanding transcatheter valve implantation (Acurate Neo 2) in a very small native aortic annulus"],"prefix":"10.3389","volume":"10","author":[{"given":"Massimo","family":"Medda","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Casilli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Bande","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maurizio","family":"Tespili","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Donatelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,9,15]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1034","DOI":"10.1161\/CIRCULATIONAHA.108.778886","article-title":"Prosthetic heart valves: selection of the optimal prosthesis and long-term management","volume":"119","author":"Pibarot","year":"2009","journal-title":"Circulation"},{"key":"B2","doi-asserted-by":"publisher","first-page":"e005013","DOI":"10.1161\/CIRCINTERVENTIONS.117.005013","article-title":"Short-term outcome and hemodynamic performance of next-generation self-expanding versus balloon-expandable transcatheter aortic valves in patients with small aortic annulus: a multicenter propensity-matched comparison","volume":"10","author":"Victor","year":"2017","journal-title":"Circ Cardiovasc Interv"},{"key":"B3","doi-asserted-by":"publisher","first-page":"196","DOI":"10.1016\/j.jcin.2019.08.041","article-title":"Transcatheter self-expandable valve implantation for aortic stenosis in small aortic annuli","volume":"13","author":"Regazzoli","year":"2020","journal-title":"JACC Cardiovasc Interv"},{"key":"B4","doi-asserted-by":"publisher","first-page":"771","DOI":"10.1016\/j.jcin.2018.01.273","article-title":"Incidence, predictors, and clinical impact of prosthesis\u2013patient mismatch following transcatheter aortic valve replacement in Asian patients: the OCEAN-TAVI registry","volume":"11","author":"Miyasaka","year":"2018","journal-title":"J Am Coll Cardiol Intv"},{"key":"B5","doi-asserted-by":"publisher","first-page":"1957","DOI":"10.1007\/s00392-021-01918-8","article-title":"Transcatheter aortic valve implantation in patients with a small aortic annulus: performance of supra-, intra- and infra-annular transcatheter heart valves","volume":"110","author":"Voigtl\u00e4nder","year":"2021","journal-title":"Clin Res Cardiol"}],"container-title":["Frontiers in Cardiovascular Medicine"],"original-title":[],"link":[{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fcvm.2023.1195486\/full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,19]],"date-time":"2023-09-19T08:56:29Z","timestamp":1695113789000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.frontiersin.org\/articles\/10.3389\/fcvm.2023.1195486\/full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,9,15]]},"references-count":5,"alternative-id":["10.3389\/fcvm.2023.1195486"],"URL":"https:\/\/doi.org\/10.3389\/fcvm.2023.1195486","relation":{},"ISSN":["2297-055X"],"issn-type":[{"type":"electronic","value":"2297-055X"}],"subject":[],"published":{"date-parts":[[2023,9,15]]},"article-number":"1195486"}}
