Bioprosthetic leaflet modification techniques that incorporate electrosurgery are evolving as the preferred strategy to mitigate the risk of CO in high CO risk settings. The UNICORN method is proposed as a more predictable leaflet modification strategy than the earlier described BASILICA approach, but its proponents have hitherto mandated the use of a balloon\u2010expandable valve (BEV) prosthesis. Many patients have small prostheses and therein face a significant risk of patient prosthesis mismatch with BEV in this setting. This risk may be curtailed if a self\u2010expanding valve (SEV) prosthesis could be used. Herein described is a modified approach to allow for the utilization of SEV systems in this setting.<\/jats:p>","DOI":"10.1002\/ccd.31195","type":"journal-article","created":{"date-parts":[[2024,9,3]],"date-time":"2024-09-03T07:20:10Z","timestamp":1725348010000},"page":"1079-1085","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["First\u2010in\u2010human: Leaflet laceration with balloon mediated annihilation to prevent coronary obstruction with radiofrequency needle (LLAMACORN) for valve\u2010in\u2010valve transcatheter aortic valve replacement"],"prefix":"10.1002","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2786-301X","authenticated-orcid":false,"given":"Christina","family":"Mew","sequence":"first","affiliation":[{"name":"Department of Cardiology Princess Alexandra Hospital Brisbane Australia"},{"name":"Faculty of Medicine University of Queensland Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arun","family":"Dahiya","sequence":"additional","affiliation":[{"name":"Department of Cardiology Princess Alexandra Hospital Brisbane Australia"},{"name":"Faculty of Medicine University of Queensland Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian A.","family":"Chong","sequence":"additional","affiliation":[{"name":"Department of Cardiology Princess Alexandra Hospital Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samual M.","family":"Hayman","sequence":"additional","affiliation":[{"name":"Department of Cardiology Princess Alexandra Hospital Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter T.","family":"Moore","sequence":"additional","affiliation":[{"name":"Department of Cardiology Princess Alexandra Hospital Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danielle L.","family":"Harrop","sequence":"additional","affiliation":[{"name":"Department of Cardiology Princess Alexandra Hospital Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Reyaldeen","sequence":"additional","affiliation":[{"name":"Department of Cardiology Princess Alexandra Hospital Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher M.
