We report three representative bicuspid TAVR cases in which static computed tomography angiography (CTA) ratios\u2010leaflet length relative to the sinotubular junction or coronary ostium\u2010yielded conflicting or borderline risk signals. Intravascular ultrasound (IVUS) directly visualized dynamic coronary compromise and guided timely protective PCI. Each case highlights a distinct scenario: discordant metrics, borderline anatomy, and overt high\u2010risk morphology. The combination of CTA and real\u2010time IVUS provided decisive risk clarification and procedural safety. This case series underscores the limitations of static anatomic assessment and demonstrates the educational value of IVUS\u2010guided decision\u2010making in complex bicuspid TAVR.<\/jats:p>","DOI":"10.1002\/ccd.70431","type":"journal-article","created":{"date-parts":[[2025,12,9]],"date-time":"2025-12-09T05:26:29Z","timestamp":1765257989000},"page":"762-766","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unveiling Hidden Threats: Intravascular Ultrasound\u2013Guided Precise Intervention for Coronary Ostium Obstruction Risk in Bicuspid Transcatheter Aortic Valve Replacement"],"prefix":"10.1002","volume":"107","author":[{"given":"Binbin","family":"Cao","sequence":"first","affiliation":[{"name":"Department of Cardiology The First Affiliated Hospital of Ningbo University Ningbo China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaoyi","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Cardiology The First Affiliated Hospital of Ningbo University Ningbo China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1498-0452","authenticated-orcid":false,"given":"Xiaomin","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Cardiology The First Affiliated Hospital of Ningbo University Ningbo China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,8]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/ehjcr\/yty112"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2022.01.003"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2022.11.018"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.21037\/qims-23-1385"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2024.01.007"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.70431","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ccd.70431","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.70431","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T03:53:25Z","timestamp":1775706805000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.70431"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,8]]},"references-count":5,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2026,2]]}},"alternative-id":["10.1002\/ccd.70431"],"URL":"https:\/\/doi.org\/10.1002\/ccd.70431","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,8]]},"assertion":[{"value":"2025-10-15","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-04","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-08","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
