Both chimney stenting and leaflet modification by BASILICA (Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Obstruction) are increasingly employed and can be highly effective means of preventing CAO. Using a case report, in which both strategies were utilized, as a platform for detailed discussion, we address the indications, contraindications, and relative merits of each technique in the prevention of CAO.<\/jats:p>","DOI":"10.1002\/ccd.30561","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T10:53:50Z","timestamp":1674039230000},"page":"655-659","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Leaflet modification or chimney stenting in patients at risk for coronary artery obstruction in valve\u2010in\u2010valve procedure for a failed surgical bioprosthetic aortic valve"],"prefix":"10.1002","volume":"101","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8496-4063","authenticated-orcid":false,"given":"Nicholas J.","family":"Montarello","sequence":"first","affiliation":[{"name":"The Heart Centre, Rigshospitalet Copenhagen University Hospital Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angelo","family":"Quagliana","sequence":"additional","affiliation":[{"name":"The Heart Centre, Rigshospitalet Copenhagen University Hospital Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lars","family":"S\u00f8ndergaard","sequence":"additional","affiliation":[{"name":"The Heart Centre, Rigshospitalet Copenhagen University Hospital Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ole","family":"De Backer","sequence":"additional","affiliation":[{"name":"The Heart Centre, Rigshospitalet Copenhagen University Hospital Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,1,18]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.113.002003"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.112.104505"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.113.000631"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2014.7246"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.07.040"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2012.11.014"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2019.04.052"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.15420\/icr.2020.08"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2018.01.247"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehx455"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2019.00120"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.4244\/EIJ-D-19-00057"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22861"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2020.01.227"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2017.06.047"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.30561","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ccd.30561","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.30561","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,22]],"date-time":"2023-08-22T18:57:07Z","timestamp":1692730627000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.30561"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,1,18]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2023,2]]}},"alternative-id":["10.1002\/ccd.30561"],"URL":"https:\/\/doi.org\/10.1002\/ccd.30561","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"type":"print","value":"1522-1946"},{"type":"electronic","value":"1522-726X"}],"subject":[],"published":{"date-parts":[[2023,1,18]]},"assertion":[{"value":"2022-10-19","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-12-17","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-01-18","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
