In 2021, the patient was diagnosed with severe aortic regurgitation and admitted to our hospital for his fourth surgery. Intraoperatively, a total of 7 perforations in all 3 valve leaflets have been observed, which were obviously induced by the rigid metallic fasteners. Redo isolated aortic valve replacement (29\u2009mm, Perimount Magna Ease, Edwards Lifesciences LLC) was performed with conventionally knotted, pledget enforced braided threads. Postoperative course was uneventful. This report shows that COR-KNOT-induced defects do not appear immediately after surgery but within the first 4 postoperative months. Since failure of aortic bioprostheses due to aortic insufficiency is often rated as \u2018early degeneration\u2019 and degenerated aortic bioprostheses are mostly replaced by valve-in-valve strategy, the true incidence of this serious complication might be underestimated. COR-KNOT should be used with caution in biological aortic valve replacement and patients should undergo close postoperative follow-ups.<\/jats:p>","DOI":"10.1093\/ejcts\/ezac357","type":"journal-article","created":{"date-parts":[[2022,6,27]],"date-time":"2022-06-27T12:34:12Z","timestamp":1656333252000},"source":"Crossref","is-referenced-by-count":2,"title":["Moth-eaten like impact of automated titanium fasteners on aortic valve bioprosthesis: a word of caution"],"prefix":"10.1093","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4493-4326","authenticated-orcid":false,"given":"David","family":"Santer","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, University Hospital Basel , Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jules","family":"Miazza","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, University Hospital Basel , Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Friedrich","family":"Eckstein","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, University Hospital Basel , Basel, Switzerland"},{"name":"Medical Faculty, University of Basel , Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,6,27]]},"reference":[{"key":"2022071316253212800_ezac357-B1","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1093\/icvts\/ivx069","article-title":"Severe aortic regurgitation after implantation of a sutureless valve prosthesis using an automatic knot fastener device","volume":"25","author":"Balan","year":"2017","journal-title":"Interact CardioVasc Thorac Surg"},{"key":"2022071316253212800_ezac357-B2","doi-asserted-by":"crossref","first-page":"e491","DOI":"10.1016\/j.athoracsur.2016.11.035","article-title":"Valvular regurgitation after implantation of prostheses secured with Cor-Knot automated fasteners","volume":"103","author":"Brescia","year":"2017","journal-title":"Ann Thorac Surg"},{"key":"2022071316253212800_ezac357-B3","doi-asserted-by":"crossref","first-page":"2987","DOI":"10.1111\/jocs.14953","article-title":"The role of Cor-Knot in the future of cardiac surgery: a systematic review","volume":"35","author":"Jenkin","year":"2020","journal-title":"J Card Surg"},{"key":"2022071316253212800_ezac357-B4","doi-asserted-by":"crossref","first-page":"20","DOI":"10.1186\/s13037-016-0107-8","article-title":"How to perform a root cause analysis for workup and future prevention of medical errors: a review","volume":"10","author":"Charles","year":"2016","journal-title":"Patient Saf Surg"},{"key":"2022071316253212800_ezac357-B5","doi-asserted-by":"crossref","first-page":"727","DOI":"10.1093\/ejcts\/ezab389","article-title":"2021 ESC\/EACTS Guidelines for the management of valvular heart disease","volume":"60","author":"Vahanian","year":"2021","journal-title":"Eur J Cardiothorac Surg"}],"container-title":["European Journal of Cardio-Thoracic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/ejcts\/advance-article-pdf\/doi\/10.1093\/ejcts\/ezac357\/44264223\/ezac357.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ejcts\/article-pdf\/62\/2\/ezac357\/44856235\/ezac357.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ejcts\/article-pdf\/62\/2\/ezac357\/44856235\/ezac357.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,7,13]],"date-time":"2022-07-13T16:30:33Z","timestamp":1657729833000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/ejcts\/article\/doi\/10.1093\/ejcts\/ezac357\/6618528"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,27]]},"references-count":5,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022,7,11]]}},"URL":"https:\/\/doi.org\/10.1093\/ejcts\/ezac357","relation":{},"ISSN":["1873-734X"],"issn-type":[{"value":"1873-734X","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2022,8,1]]},"published":{"date-parts":[[2022,6,27]]},"article-number":"ezac357"}}
