As the population ages, the number of patients at risk for aortic valve reoperation constantly increases. The aim of the present study is to present our single-center experience in sutureless aortic valve replacement (SU-AVR) in reoperations. Materials and Methods: The data of 18 consecutive patients who underwent SU-AVR in a reoperation between May 2020 and January 2023 were retrospectively analyzed. Results: The mean age of the patients was 67.9 \u00b1 11.1 years; patients showed a moderate-risk profile with a median logistic EuroSCORE II of 7.8 (IQR of 3.8\u201332.0) %. The implantation of the Perceval S prosthesis was technically successful in all patients. The mean cardiopulmonary bypass time was 103.3 \u00b1 50.0 min, and the cross-clamp time was 69.1 \u00b1 38.8 min. No patients required a permanent pacemaker implantation. The postoperative gradient was 7.3 \u00b1 2.4 mmHg, and no cases of paravalvular leakage were observed. There was one case of intraprocedural death, while the thirty-day mortality was 11%. Conclusions: Sutureless bioprosthetic valves tend to simplify the surgical procedure of a redo AVR. By maximizing the effective orifice area, sutureless valves may present an important advantage, being a safe and effective alternative not only to traditional surgical prostheses but also to transcatheter valve-in-valve approaches in select cases.<\/jats:p>","DOI":"10.3390\/medicina59061126","type":"journal-article","created":{"date-parts":[[2023,6,12]],"date-time":"2023-06-12T01:28:21Z","timestamp":1686533301000},"page":"1126","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Sutureless Aortic Valve Prosthesis in Redo Procedures: Single-Center Experience"],"prefix":"10.3390","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2444-5747","authenticated-orcid":false,"given":"Alina","family":"Zubarevich","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, West German Heart and Vascular Center, University of Duisburg-Essen, Hufelandstra\u00dfe 55, 45122 Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eleftherios T.","family":"Beltsios","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, West German Heart and Vascular Center, University of Duisburg-Essen, Hufelandstra\u00dfe 55, 45122 Essen, Germany"},{"name":"Department of Cardiothoracic, Transplant and Vascular Surgery, Hannover Medical School, 30625 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4931-4049","authenticated-orcid":false,"given":"Arian","family":"Arjomandi Rad","sequence":"additional","affiliation":[{"name":"Medical Sciences Division, University of Oxford, Oxford OX3 9DU, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lukman","family":"Amanov","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, West German Heart and Vascular Center, University of Duisburg-Essen, Hufelandstra\u00dfe 55, 45122 Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0711-7354","authenticated-orcid":false,"given":"Marcin","family":"Szczechowicz","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, West German Heart and Vascular Center, University of Duisburg-Essen, Hufelandstra\u00dfe 55, 45122 Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arjang","family":"Ruhparwar","sequence":"additional","affiliation":[{"name":"Medical Sciences Division, University of Oxford, Oxford OX3 9DU, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Weymann","sequence":"additional","affiliation":[{"name":"Medical Sciences Division, University of Oxford, Oxford OX3 9DU, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1016\/j.jtcvs.2008.08.015","article-title":"Isolated aortic valve replacement in North America comprising 108,687 patients in 10 years: Changes in risks, valve types, and outcomes in the Society of Thoracic Surgeons National Database","volume":"137","author":"Brown","year":"2009","journal-title":"J.
