We previously described unusual mobile filamentous structures in the carotid artery. Here, we describe similar findings in the aorta and their possible cause.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>An 88-year-old female with progressive exertional dyspnoea and severe aortic stenosis had a successful transcatheter aortic valve replacement (TAVR). A filamentous structure was noted on the focused pre-operative 2D transoesophageal echocardiography in the proximal descending aorta and post-TAVR as long strand-like structures attached to the thickened intimal wall with a planar component on 3D imaging. These findings were not associated with symptoms or clinical sequelae on short- and long-term follow-up.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>The mobile structures that we describe are atypical for atheroma, thrombi, vegetations, and dissections in terms of their form and clinical presentation. 2D imaging showed that the filaments had focal thickening and emerged from the aortic surface. These findings suggest a relationship with the intima, perhaps from atherogenesis or injury with disruption or lifting of the intimal surface. No clinical sequelae were detected that may also relate to their position in the descending aorta and not the arch.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytae263","type":"journal-article","created":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T20:43:58Z","timestamp":1716497038000},"source":"Crossref","is-referenced-by-count":0,"title":["The enigma of fine mobile structures on the aortic surface in a patient undergoing transcatheter aortic valve replacement: a case report"],"prefix":"10.1093","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8261-0395","authenticated-orcid":false,"given":"Gerald I","family":"Cohen","sequence":"first","affiliation":[{"name":"Department of Cardiology, Ascension St. John Hospital , 22101 Moross Road, Detroit, MI 48236 , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karim","family":"Saleb","sequence":"additional","affiliation":[{"name":"IU Health Ball Memorial Physicians Cardiology , 2525 W University Ave. Suite 300, Muncie, IN 47303 , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Troy","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ascension St. John Hospital , 22101 Moross Road, Detroit, MI 48236 , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klaus D","family":"Hagspiel","sequence":"additional","affiliation":[{"name":"Department of Radiology and Medical Imaging, University of Virginia Health System , 1215 Lee St. 1st Floor, Charlottesville, VA 22903 , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Lalonde","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ascension St. John Hospital , 22101 Moross Road, Detroit, MI 48236 , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2024,5,27]]},"reference":[{"key":"2024062814450122700_ytae263-B1","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/0735-1097(91)90706-F","article-title":"Recognition and embolic potential of intraaortic atherosclerotic debris","volume":"17","author":"Karalis","year":"1991","journal-title":"J Am Coll Cardiol"},{"key":"2024062814450122700_ytae263-B2","doi-asserted-by":"crossref","first-page":"882","DOI":"10.1016\/S0894-7317(96)90483-6","article-title":"Transesophageal echocardiographic findings in blue toe syndrome exacerbated by anticoagulation","volume":"9","author":"Willens","year":"1996","journal-title":"J Am Soc Echocardiogr"},{"key":"2024062814450122700_ytae263-B3","doi-asserted-by":"crossref","first-page":"i31","DOI":"10.1093\/ejechocard\/jen251","article-title":"Echocardiography in the emergency assessment of acute aortic syndromes","volume":"10","author":"Meredith","year":"2009","journal-title":"Eur J Echocardiogr"},{"key":"2024062814450122700_ytae263-B4","first-page":"343","article-title":"Carotid strands: possible mechanisms and implications of a novel finding","volume":"4","author":"Cohen","year":"2020","journal-title":"CASE (Philadelphia, Pa.)"},{"key":"2024062814450122700_ytae263-B5","first-page":"232","article-title":"Screening asymptomatic subjects with subclinical arteriosclerotic lesions with arterial ultrasonic biopsy","volume":"22","author":"Belcaro","year":"1993","journal-title":"The P.A.P. study.
