A 85\u2010year\u2010old female (<jats:styled-content style=\"fixed-case\">NYHA<\/jats:styled-content> I\u2013<jats:styled-content style=\"fixed-case\">II<\/jats:styled-content>) was hospitalized for investigations. An echocardiogram showed calcification of the <jats:styled-content style=\"fixed-case\">MV<\/jats:styled-content> with mild stenosis and moderate regurgitation. Transesophageal three\u2010dimensional echocardiogram revealed a band\u2010like structure extending from the distal third of the anterior wall of the left atrium to the <jats:styled-content style=\"fixed-case\">MV<\/jats:styled-content>. This accessory chordae determined severe systolic regurgitation and mild mitral stenosis. The patient was referred for consideration of cardiac surgery but was refused for comorbidities and anatomy. Usually aberrant chordae determinant valvulopathies are detected and treated at a much younger age. The delay of the symptoms could be explained in our case with the progressive growth and dilatation of the left atrium causing traction of the aberrant chord resulting in an increase in the leaflet prolapse and regurgitation.<\/jats:p>","DOI":"10.1111\/echo.13869","type":"journal-article","created":{"date-parts":[[2018,3,23]],"date-time":"2018-03-23T05:12:43Z","timestamp":1521781963000},"page":"750-752","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A late presentation of congenital cardiac anomaly: Accessory chordae from the left atrium causing severe mitral regurgitation"],"prefix":"10.1111","volume":"35","author":[{"given":"Giovanni","family":"D'Onghia","sequence":"first","affiliation":[{"name":"Cardiology Trento Hospital  Trento Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5696-2351","authenticated-orcid":false,"given":"Marta","family":"Martin","sequence":"additional","affiliation":[{"name":"Cardiology Trento Hospital  Trento Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Teresa","family":"Mancini","sequence":"additional","affiliation":[{"name":"Cardiology Trento Hospital  Trento Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvia","family":"Quintarelli","sequence":"additional","affiliation":[{"name":"Cardiology Trento Hospital  Trento Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adele","family":"Cozza","sequence":"additional","affiliation":[{"name":"Cardiology Trento Hospital  Trento Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabrizio","family":"Guarracini","sequence":"additional","affiliation":[{"name":"Cardiology Trento Hospital  Trento Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Bonmassari","sequence":"additional","affiliation":[{"name":"Cardiology Trento Hospital  Trento Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,3,22]]},"reference":[{"key":"e_1_2_2_2_1","first-page":"187","article-title":"Clinicopathologic study of mitral regurgitation due to abnormal chordae tendinae","volume":"27","author":"Kuboki K","year":"1996","journal-title":"J Cardiol"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2007.07.002"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2008.05.058"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcts.2010.02.036"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8191.2010.01076.x"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2011.01599.x"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/jscr\/2011.5.1"}],"container-title":["Echocardiography"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fecho.13869","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/echo.13869","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,23]],"date-time":"2023-09-23T15:47:29Z","timestamp":1695484049000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/echo.13869"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,3,22]]},"references-count":7,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2018,5]]}},"alternative-id":["10.1111\/echo.13869"],"URL":"https:\/\/doi.org\/10.1111\/echo.13869","archive":["Portico"],"relation":{},"ISSN":["0742-2822","1540-8175"],"issn-type":[{"value":"0742-2822","type":"print"},{"value":"1540-8175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,3,22]]},"assertion":[{"value":"2018-03-22","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
