This study evaluated early postoperative outcomes as a preliminary analysis.<\/jats:p><jats:p>\n          Methods\u2003The primary end point of the trial was the mean pressure gradient across the aortic valve (AVMPG) at 1 year after surgery. Patients were screened to enroll 70 patients in each group based on a noninferiority design. Early postoperative hemodynamic and clinical outcomes were compared between the two groups.<\/jats:p><jats:p>\n          Results\u2003There were no differences in baseline characteristics, including sex and body surface area (1.64\u2009\u00b1\u20090.18 vs. 1.65\u2009\u00b1\u20090.15 m2) between the two groups. The AVMPG on early postoperative echocardiography was 15.2\u2009\u00b1\u20094.6\u2009mm Hg and 16.5\u2009\u00b1\u20096.2\u2009mm Hg in the study and control groups, respectively (p\u2009=\u20090.177). Although AVMPG of the 19\u2009mm prostheses was lower in the study group than in the control group (17.0\u2009\u00b1\u20096.3\u2009mm Hg vs. 22.8\u2009\u00b1\u20096.6\u2009mm Hg, p\u2009=\u20090.039), there were no significant differences in the effective orifice area in all patients (1.57\u2009\u00b1\u20090.41\u2009cm2 vs. 1.53\u2009\u00b1\u20090.34\u2009cm2, p\u2009=\u20090.568), and each valve size. The effective orifice area index was also similar between the two groups in overall (p\u2009=\u20090.352), and in each valve size. There were no significant differences in clinical outcomes including operative mortality and postoperative complications between the two groups.<\/jats:p><jats:p>\n          Conclusion\u2003Early postoperative hemodynamic and clinical results after AVR using a recently introduced bovine pericardial valve were comparable with those using the control valve (NCT03796442)<\/jats:p>","DOI":"10.1055\/s-0042-1753494","type":"journal-article","created":{"date-parts":[[2022,8,2]],"date-time":"2022-08-02T22:44:22Z","timestamp":1659480262000},"page":"648-655","source":"Crossref","is-referenced-by-count":0,"title":["Preliminary Report from a Randomized Controlled Trial Comparing Two Bovine Pericardial Valves"],"prefix":"10.1055","volume":"71","author":[{"given":"Suk Ho","family":"Sohn","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji Seong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae Woong","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4769-5340","authenticated-orcid":false,"given":"Jae Hang","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Seoul National University Bundang Hospital, Seongnam, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun Sung","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Seoul National University Bundang Hospital, Seongnam, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheong","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Seoul National University Bundang Hospital, Seongnam, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ho Young","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,8,2]]},"reference":[{"issue":"05","key":"ref1","first-page":"e72","article-title":"2020 ACC\/AHA Guideline for the Management of Patients With Valvular Heart Disease: A Report of the American College of Cardiology\/American Heart Association Joint Committee on Clinical Practice Guidelines","volume":"143","author":"C M Otto","year":"2021","journal-title":"Circulation"},{"issue":"36","key":"ref2","doi-asserted-by":"crossref","first-page":"2739","DOI":"10.1093\/eurheartj\/ehx391","article-title":"2017 ESC\/EACTS Guidelines for the management of valvular heart disease","volume":"38","author":"H Baumgartner","year":"2017","journal-title":"Eur Heart J"},{"issue":"03","key":"ref3","doi-asserted-by":"crossref","first-page":"425","DOI":"10.1093\/ejcts\/ezx066","article-title":"Safety, effectiveness and haemodynamic performance of a new stented aortic valve bioprosthesis","volume":"52","author":"R JM Klautz","year":"2017","journal-title":"Eur J Cardiothorac Surg"},{"issue":"04","key":"ref4","doi-asserted-by":"crossref","first-page":"1368","DOI":"10.1016\/j.jtcvs.2018.03.171","article-title":"One-year outcomes associated with a novel stented bovine pericardial aortic bioprosthesis","volume":"156","author":"J F Sabik III","year":"2018","journal-title":"J Thorac Cardiovasc Surg"},{"issue":"02","key":"ref5","doi-asserted-by":"crossref","first-page":"371","DOI":"10.1016\/j.jtcvs.2019.07.132","article-title":"Safety, efficacy, and hemodynamic performance of a stented bovine pericardial aortic valve bioprosthesis: two-year analysis","volume":"160","author":"F Dagenais","year":"2020","journal-title":"J Thorac Cardiovasc Surg"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"66","DOI":"10.1016\/j.jtcvs.2019.10.095","article-title":"Antithrombotic therapy and bleeding events after aortic valve replacement with a novel bioprosthesis","volume":"161","author":"R JM Klautz","year":"2019","journal-title":"J Thorac Cardiovasc Surg"},{"issue":"08","key":"ref7","doi-asserted-by":"crossref","first-page":"649","DOI":"10.1001\/jama.1996.03540080071033","article-title":"How to report randomized controlled trials.
