CT showed chronic type B aortic dissection (TBAD) between the distal aortic arch and the left common iliac artery. After careful consideration, we planned transfemoral (TF)-transcatheter aortic valve implantation (TAVI) using a 20-Fr long sheath to minimise number of contacts with the false lumen of the aorta. TAVI was performed under general anaesthesia, guided by transoesophageal echocardiography (TEE). A transcatheter aortic valve was successfully implanted. TEE immediately after valve implantation showed no remarkable changes in the descending thoracic aorta. Repeated postprocedural CT examinations showed no obvious changes in the aorta. The patient was stable without sequelae at the 12-month follow-up. This case demonstrates that TF-TAVI using a long sheath under TEE guidance can be a treatment option for patients with severe AS and chronic TBAD.<\/jats:p>","DOI":"10.1136\/bcr-2021-246847","type":"journal-article","created":{"date-parts":[[2022,1,17]],"date-time":"2022-01-17T10:50:27Z","timestamp":1642416627000},"page":"e246847","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Transfemoral transcatheter aortic valve implantation in a patient with chronic type B aortic dissection"],"prefix":"10.1136","volume":"15","author":[{"given":"Masaki","family":"Tsuda","sequence":"first","affiliation":[{"name":"Cardiology, Osaka Rosai Hospital, Sakai, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasuyuki","family":"Egami","sequence":"additional","affiliation":[{"name":"Cardiology, Osaka Rosai Hospital, Sakai, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0309-7023","authenticated-orcid":false,"given":"Masami","family":"Nishino","sequence":"additional","affiliation":[{"name":"Cardiology, Osaka Rosai Hospital, Sakai, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Tanouchi","sequence":"additional","affiliation":[{"name":"Cardiology, Osaka Rosai Hospital, Sakai, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,1,17]]},"reference":[{"key":"2025082703135671000_15.1.e246847.1","first-page":"E184","article-title":"Trends and outcomes of alternative-access transcatheter aortic valve replacement","volume":"31","author":"Pineda","year":"2019","journal-title":"J Invasive Cardiol"},{"key":"2025082703135671000_15.1.e246847.2","first-page":"1452","article-title":"Transcarotid versus transfemoral access in patients undergoing transcatheter aortic valve replacement with complex aortofemoral anatomy","volume":"97","author":"Leclercq","year":"2021","journal-title":"Catheter Cardiovasc Interv"},{"key":"2025082703135671000_15.1.e246847.3","doi-asserted-by":"crossref","DOI":"10.1186\/s13019-020-01291-z","article-title":"Safety and efficacy of transaxillary transcatheter aortic valve replacement using a current-generation balloon-expandable valve","volume":"15","author":"Zhan","year":"2020","journal-title":"J Cardiothorac Surg"},{"key":"2025082703135671000_15.1.e246847.4","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.25986"},{"key":"2025082703135671000_15.1.e246847.5","doi-asserted-by":"crossref","first-page":"1345","DOI":"10.1016\/j.jvs.2017.08.098","article-title":"Outcomes of thoracic endovascular aortic repair for chronic aortic dissections","volume":"67","author":"Conway","year":"2018","journal-title":"J Vasc Surg"},{"key":"2025082703135671000_15.1.e246847.6","doi-asserted-by":"crossref","first-page":"772","DOI":"10.1111\/jocs.15297","article-title":"A report of transcatheter aortic valve insertion in a patient with chronic type B aortic dissection","volume":"36","author":"Schumer","year":"2021","journal-title":"J Card Surg"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2021-246847","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T10:14:02Z","timestamp":1756289642000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2021-246847"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,1]]},"references-count":6,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,1,17]]},"published-print":{"date-parts":[[2022,1]]}},"alternative-id":["10.1136\/bcr-2021-246847"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2021-246847","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,1]]}}}
