Coronary ostia obstruction is a rare but a life\u2010threatening complication of TAVR. In case of suspected coronary ostia obstruction, intravascular ultrasound study (IVUS) assessment could be feasible and useful to evaluate coronary ostia patency after the transcatheter aortic valve deployment, in high\u2010risk scenarios for coronary occlusion. We described the case of a 73\u2010year\u2010old female with delayed coronary obstruction after TAVR with a 23\u2010mm SAPIEN 3 ULTRA who underwent IVUS\u2010guided percutaneous coronary intervention, using the chimney stenting technique, due to critical ostium left main impingement.<\/jats:p>","DOI":"10.1002\/ccd.30116","type":"journal-article","created":{"date-parts":[[2022,2,3]],"date-time":"2022-02-03T20:35:25Z","timestamp":1643920525000},"page":"1687-1690","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Usefulness of intravascular ultrasound to assess coronary occlusion after transcatheter aortic valve replacement"],"prefix":"10.1002","volume":"99","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7084-188X","authenticated-orcid":false,"given":"Roberto","family":"Valvo","sequence":"first","affiliation":[{"name":"Division of Cardiology C.A.S.T., Azienda Ospedaliero\u2010Universitaria \u201cPoliclinico G.
