Depending on deceleration time (DT) and isovolumetric relaxation time (IVRT) with preoperative echocardiographic assessment, patients were divided into two groups: restrictive physiology (DT \u2264 150 msec and IVRT &lt; 100 msec, 20 patients), and nonrestrictive physiology (DT &gt; 150 msec and IVRT \u2265 100 msec, 27 patients). Although left ventricular mass index signif icantly decreased in both groups, improvement in DT, IVRT, and ejection fraction occurred only in patients with restrictive physiology. As a result, the patients with restrictive diastolic characteristics had more benefit than the patients with nonrestrictive physiology after aortic valve replacement.<\/jats:p>","DOI":"10.1177\/000331970305400604","type":"journal-article","created":{"date-parts":[[2008,7,28]],"date-time":"2008-07-28T17:57:07Z","timestamp":1217267827000},"page":"655-659","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of Changes in Diastolic Functions After Aortic Valve Replacement with Freestyle Stentless Porcine Xenografts in Patients with Restrictive and Nonrestrictive Physiology"],"prefix":"10.1177","volume":"54","author":[{"given":"Mustafa \u00d6zcan","family":"Soylu","sequence":"first","affiliation":[{"name":"Department of Cardiology, T\u00fcrkiye Y\u00fcksek \u0130htisas Hospital, Ankara, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmet Duran","family":"Demir","sequence":"additional","affiliation":[{"name":"Department of Cardiology, T\u00fcrkiye Y\u00fcksek \u0130htisas Hospital, Ankara, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00d6zcan","family":"\u00d6zdemir","sequence":"additional","affiliation":[{"name":"Department of Cardiology, T\u00fcrkiye Y\u00fcksek \u0130htisas Hospital, Ankara, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y\u00fccel","family":"Uzun","sequence":"additional","affiliation":[{"name":"Department of Cardiology, T\u00fcrkiye Y\u00fcksek \u0130htisas Hospital, Ankara, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ay\u015feg\u00fcl","family":"Kunt","sequence":"additional","affiliation":[{"name":"Department of Cardiology, T\u00fcrkiye Y\u00fcksek \u0130htisas Hospital, Ankara, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u015eule","family":"Korkmaz","sequence":"additional","affiliation":[{"name":"Department of Cardiology, T\u00fcrkiye Y\u00fcksek \u0130htisas Hospital, Ankara, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oguz","family":"Ta\u015fdemir","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, T\u00fcrkiye Y\u00fcksek \u0130htisas Hospital, Ankara, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2003,11,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(76)90491-4"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1177\/000331970105200104"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.68.12.608"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(96)70001-6"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(99)80084-8"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(94)70144-X"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(95)00639-7"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(98)01119-9"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(88)90416-0"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-6196(12)65305-1"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.1992.tb00486.x"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1016\/S0894-7317(14)80041-2"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(99)00215-5"},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(96)00438-9"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00144-7"},{"key":"atypb16","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(96)00496-2"},{"key":"atypb17","first-page":"73","volume":"87","author":"Hess OM","year":"1993","journal-title":"Circulation"}],"container-title":["Angiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000331970305400604","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/000331970305400604","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T10:13:05Z","timestamp":1777371185000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/000331970305400604"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,11]]},"references-count":17,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2003,11]]}},"alternative-id":["10.1177\/000331970305400604"],"URL":"https:\/\/doi.org\/10.1177\/000331970305400604","relation":{},"ISSN":["0003-3197","1940-1574"],"issn-type":[{"value":"0003-3197","type":"print"},{"value":"1940-1574","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,11]]}}}
