We set the primary endpoint as the new development of ADHF within 72\u2009hours after TAVI, and clinical indices associated with it were evaluated using a multivariable logistic model. The median age of the patients was 83 (quartile range 80\u201386) years, 48 (30.8%) were men and the median Society of Thoracic Surgery-Predicted Risk of Mortality was 7.1 (range 5.2\u201310.4). Mitral stenosis (MS), defined as mean transmitral valve pressure gradient \u22655\u2009mm Hg, was present in 15 (9.6%) patients. After TAVI, the invasive mean transaortic valve pressure gradient (mAVPG) decreased from 48 (36\u201366) to 7 (5\u201311) mm Hg, and 12 (7.7%) patients developed ADHF within 72\u2009hours after TAVI. Multivariable logistic regression analysis showed that MS (adjusted OR, 14.227; 95% CI 2.654 to 86.698; p=0.002) and greater decreases in mAVPG (1.038; 1.003 to 1.080; p=0.044) were associated with ADHF.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>MS and drastic improvement of mAVPG were associated with new development of ADHF within 72\u2009hours after TAVI.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/openhrt-2020-001348","type":"journal-article","created":{"date-parts":[[2020,10,5]],"date-time":"2020-10-05T17:28:36Z","timestamp":1601918916000},"page":"e001348","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Presence of mitral stenosis is a risk factor of new development of acute decompensated heart failure early after transcatheter aortic valve implantation"],"prefix":"10.1136","volume":"7","author":[{"given":"Tsukasa","family":"Okai","sequence":"first","affiliation":[{"name":"Cardiovascular Medicine, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7206-4538","authenticated-orcid":false,"given":"Kazuki","family":"Mizutani","sequence":"additional","affiliation":[{"name":"Cardiology, Kindai University Faculty of Medicine, Osakasayama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiko","family":"Hara","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Shimane University Faculty of Medicine Graduate School of Medicine, Izumo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiro","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mana","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asahiro","family":"Ito","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinichi","family":"Iwata","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasuhiro","family":"Izumiya","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yosuke","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Cardiovascular Surgery, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihiko","family":"Shibata","sequence":"additional","affiliation":[{"name":"Cardiovascular Surgery, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minoru","family":"Yoshiyama","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, Osaka City University, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,10,5]]},"reference":[{"key":"2025081709574108000_7.2.e001348.1","doi-asserted-by":"publisher","DOI":"10.4065\/mcp.2009.0706"},{"key":"2025081709574108000_7.2.e001348.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2014.02.536"},{"key":"2025081709574108000_7.2.e001348.3","doi-asserted-by":"crossref","first-page":"1695","DOI":"10.1056\/NEJMoa1814052","article-title":"Transcatheter aortic-valve replacement with a balloon-expandable valve in low-risk patients","volume":"380","author":"Mack","year":"2019","journal-title":"N Engl J Med"},{"key":"2025081709574108000_7.2.e001348.4","doi-asserted-by":"crossref","first-page":"1706","DOI":"10.1056\/NEJMoa1816885","article-title":"Evolut Low Risk Trial Investigators.
