The median time between TEE during TAVR (TEE\/TAVR) and TTE was 4 days (IQR 2-10 days). After TAVR, 48% of the patients had at least trace AR by TEE, 56% by angiography and 67% by TTE. The majority of AR was paravalvular (78%). More patients were classified with mild-to-moderate AR by TTE than by TEE (44 vs. 22%, &lt;i&gt;p&lt;\/i&gt; &lt; 0.01). When examining the 46 patients with AR by TTE which was not at TEE\/TAVR, both systolic and diastolic blood pressure (SBP and DBP) were significantly higher during TTE than during TEE (mean &amp;#x0394;SBP = 9 \u00b1 4 mm Hg and mean &amp;#x0394;DBP = 6 \u00b1 2 mm Hg, &lt;i&gt;p&lt;\/i&gt; &lt; 0.01 for both). No differences in BP between TEE and TTE were found among patients with no AR or among those who had AR in both studies. At a median follow-up of 185 days (IQR 39-424 days), the overall mortality was 17%, but this was not associated with the presence of AR on TTE or TEE. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Patients' hemodynamic conditions may result in underdiagnosis of paravalvular regurgitation in periprocedural TEE. Our findings suggest that a postprocedural evaluation for AR by TTE could serve as a reasonable alternative to TEE for the evaluation of AR.<\/jats:p>","DOI":"10.1159\/000452617","type":"journal-article","created":{"date-parts":[[2016,12,7]],"date-time":"2016-12-07T22:03:58Z","timestamp":1481148238000},"page":"1-8","source":"Crossref","is-referenced-by-count":11,"title":["Transthoracic Echocardiography to Assess Aortic Regurgitation after TAVR: A Comparison with Periprocedural Transesophageal Echocardiography"],"prefix":"10.1159","volume":"137","author":[{"given":"Alexandra","family":"Goncalves","sequence":"first","affiliation":[]},{"given":"Charles","family":"Nyman","sequence":"additional","affiliation":[]},{"given":"David R.","family":"Okada","sequence":"additional","affiliation":[]},{"given":"Avinainder","family":"Singh","sequence":"additional","affiliation":[]},{"given":"Jeffrey","family":"Swanson","sequence":"additional","affiliation":[]},{"given":"Michael","family":"Cheezum","sequence":"additional","affiliation":[]},{"given":"Michael","family":"Steigner","sequence":"additional","affiliation":[]},{"given":"Marcelo","family":"Di Carli","sequence":"additional","affiliation":[]},{"given":"Scott","family":"Solomon","sequence":"additional","affiliation":[]},{"given":"Pinak B.","family":"Shah","sequence":"additional","affiliation":[]},{"given":"Deepak L.","family":"Bhatt","sequence":"additional","affiliation":[]},{"given":"Douglas","family":"Shook","sequence":"additional","affiliation":[]},{"given":"Ron","family":"Blankstein","sequence":"additional","affiliation":[]}],"member":"127","published-online":{"date-parts":[[2016,12,8]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1200384"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1114705"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMc1408396"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.01.047"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2006.01.049"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.106.677237"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2014.05.014"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcmg.2015.01.008"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1093\/ejechocard\/jeq031"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1093\/ejechocard\/jep007"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.2307\/2529310"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehu384"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2015.01.007"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2014.02.556"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(99)00644-X"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.11.048"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2014.10.067"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(99)00314-9"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.25778"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2011.07.003"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2009.07.005"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2012.11.010"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2015.01.009"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2012.03.017"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2011.08.019"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2014.02.038"}],"container-title":["Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/452617","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/452617","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/452617","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:23:36Z","timestamp":1745429016000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000452617"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,12,8]]},"references-count":26,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2017,4,6]]}},"URL":"https:\/\/doi.org\/10.1159\/000452617","archive":["Portico"],"relation":{},"ISSN":["0008-6312","1421-9751"],"issn-type":[{"type":"print","value":"0008-6312"},{"type":"electronic","value":"1421-9751"}],"subject":[],"published":{"date-parts":[[2016,12,8]]}}}
