We present the case of a 70-year-old female with a prior 19mm bioprosthetic aortic valve replacement who, during routine follow-up, was found to have significant aortic valve stenosis, severely reduced leaflet mobility and a mean gradient of 40mmHg. Pre-operative computed tomography angiography revealed a calcified \u2018porcelain aorta\u2019. Transcatheter aortic valve-in-valve replacement was not possible due to the small 19mm valve and small aortic sinuses, leading to referral for open aortic surgery.<\/jats:p>","DOI":"10.1510\/mmcts.2025.119","type":"journal-article","created":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T12:41:15Z","timestamp":1760964075000},"source":"Crossref","is-referenced-by-count":0,"title":["Open aortic root in a porcelain aorta when TAVR is not feasible"],"prefix":"10.1510","member":"10966","published-online":{"date-parts":[[2025,10,20]]},"container-title":["Multimedia Manual of Cardio-Thoracic Surgery"],"original-title":[],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T12:41:16Z","timestamp":1760964076000},"score":1,"resource":{"primary":{"URL":"https:\/\/mmcts.org\/case-report\/2111"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,20]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1510\/mmcts.2025.119","relation":{},"ISSN":["1813-9175"],"issn-type":[{"value":"1813-9175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,20]]}}}
