However, limited benchmark data are available regarding the long-term outcomes in patients treated with surgical aortic valve replacement (SAVR). We investigated the long-term outcomes of SAVR using a 19-mm bioprosthesis.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>This study included consecutive patients who underwent SAVR using a 19-mm bioprosthesis at our hospital between 2008 and 2012.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>In a total of 132 patients, moderate and severe prosthesis\u2013patient mismatch occurred in 36 (27.3%) and 7 patients (5.3%), respectively. The median follow-up period was 7.7\u2009years. The overall 5- and 10-year survival rates were 79.4% and 52.9%, respectively. The 5- and 10-year freedom from major adverse valve-related events rates were 89.6% and 74.2%, respectively. Neither moderate nor severe prosthesis\u2013patient mismatch was associated with late mortality, major adverse valve-related events or heart failure. Follow-up echocardiographic data were obtained at a median interval of 4.8\u2009years in 80% of patients who survived \u22656\u2009months postoperatively. Follow-up echocardiographic data showed a significantly increased left ventricular ejection fraction, decreased mean transvalvular\/transprosthetic pressure gradients and a decreased mean left ventricular mass. At follow-up, we observed moderate or severe haemodynamic structural valve deterioration in 17 patients; however, structural valve deterioration did not affect late survival or freedom from major adverse valve-related events rates, or heart failure.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>SAVR using the 19-mm bioprosthesis was associated with satisfactory long-term clinical and haemodynamic outcomes.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ejcts\/ezab379","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T19:12:23Z","timestamp":1627499543000},"page":"625-634","source":"Crossref","is-referenced-by-count":3,"title":["Long-term outcomes after aortic valve replacement using a 19-mm bioprosthesis"],"prefix":"10.1093","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8806-5110","authenticated-orcid":false,"given":"Homare","family":"Okamura","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Medical Center, Jichi Medical University, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sho","family":"Kusadokoro","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Medical Center, Jichi Medical University, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makiko","family":"Mieno","sequence":"additional","affiliation":[{"name":"Department of Medical Informatics, Center for Information, Jichi Medical University, Tochigi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2618-6934","authenticated-orcid":false,"given":"Naoyuki","family":"Kimura","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Medical Center, Jichi Medical University, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3776-2394","authenticated-orcid":false,"given":"Atsushi","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Medical Center, Jichi Medical University, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,8,25]]},"reference":[{"key":"2022022016300654500_ezab379-B1","doi-asserted-by":"crossref","first-page":"1131","DOI":"10.1016\/S0735-1097(00)00859-7","article-title":"Hemodynamic and clinical impact of prosthesis-patient mismatch in the aortic valve position and its prevention","volume":"36","author":"Pibarot","year":"2000","journal-title":"J Am Coll Cardiol"},{"key":"2022022016300654500_ezab379-B2","doi-asserted-by":"crossref","first-page":"416","DOI":"10.1016\/j.jtcvs.2019.05.081","article-title":"Surgical valve selection in the era of transcatheter aortic valve replacement in the Society of Thoracic Surgeons Database","volume":"159","author":"Tam","year":"2020","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2022022016300654500_ezab379-B3","doi-asserted-by":"crossref","first-page":"1239","DOI":"10.1016\/j.athoracsur.2014.10.070","article-title":"Long-term durability of bioprosthetic aortic valve: implications from 12,569 implants","volume":"99","author":"Johnston","year":"2015","journal-title":"Ann Thorac Surg"},{"key":"2022022016300654500_ezab379-B4","doi-asserted-by":"crossref","first-page":"1513","DOI":"10.1253\/circj.CJ-10-0557","article-title":"Transcatheter aortic valve implantation in high-risk patients with severe aortic stenosis","volume":"74","author":"Hara","year":"2010","journal-title":"Circ J"},{"key":"2022022016300654500_ezab379-B5","doi-asserted-by":"crossref","first-page":"1323","DOI":"10.1016\/j.jacc.2014.06.1195","article-title":"Incidence and sequelae of prosthesis-patient mismatch in transcatheter versus surgical valve replacement in high-risk patients with severe aortic stenosis: a PARTNER trial cohort\u2014a analysis","volume":"64","author":"Pibarot","year":"2014","journal-title":"J Am Coll Cardiol"},{"key":"2022022016300654500_ezab379-B6","doi-asserted-by":"crossref","first-page":"2685","DOI":"10.1161\/CIRCULATIONAHA.118.038408","article-title":"Aortic stenosis and small aortic annulus","volume":"139","author":"Freitas-Ferraz","year":"2019","journal-title":"Circulation"},{"key":"2022022016300654500_ezab379-B7","doi-asserted-by":"crossref","first-page":"613","DOI":"10.1161\/01.CIR.55.4.613","article-title":"Echocardiographic determination of left ventricular mass in man.
