There were 50 (64.9%) men and 27 (35.1%) women. Mean age was 68.7 \u00b1 11.1 years. The surgical procedure used a complete root replacement. Concomitant procedures included coronary artery bypass grafting in 15 (19.5%) patients.\r\nResults: The mean cardiopulmonary bypass time was 130.3 \u00b1 26.4 minutes and total aortic cross clamp time was 99.5 \u00b1 23.6 minutes. Hospital mortality was 2.6%. The median follow-up time was 11.2 years. The 5- and 10-years freedom from aortic valve reoperation were 97.4 \u00b1 1.2% and 93.4 \u00b1 4.9%, respectively. During 10 years follow up, there were 14 late deaths; 4 deaths were cardiac, and 10 deaths were noncardiac. Valve-related deaths were attributable to thromboembolism in 1 patient, endocarditis in 2 patients, and congestive heart failure in 1 patient.\r\nConclusion: The freestyle stentless aortic root bioprosthesis offered good clinical outcomes, in terms of survival and structural valve deterioration. The Freestyle valve is a viable option for use in patients undergoing bioprosthetic aortic valve replacement and expected desire for long-term durability.<\/jats:p>","DOI":"10.1532\/hsf.2661","type":"journal-article","created":{"date-parts":[[2020,2,10]],"date-time":"2020-02-10T18:04:31Z","timestamp":1581357871000},"page":"E034-E038","source":"Crossref","is-referenced-by-count":2,"title":["Long Term Outcomes of Freestyle Stentless Aortic Bioprosthesis:  A Single Center Experience"],"prefix":"10.31083","volume":"23","author":[{"given":"Mehmet","family":"Ezelsoy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kerem","family":"Oral","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kemal Tolga","family":"Saracoglu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayten","family":"Saracoglu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zehra","family":"Bayramoglu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Belhhan","family":"Akpinar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2020,2,10]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/2661\/4201","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/2661\/4201","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T10:14:49Z","timestamp":1766398489000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/23\/1\/10.1532\/hsf.2661"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,2,10]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2020,1,23]]}},"URL":"https:\/\/doi.org\/10.1532\/hsf.2661","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"type":"electronic","value":"1522-6662"},{"type":"print","value":"1098-3511"}],"subject":[],"published":{"date-parts":[[2020,2,10]]}}}
