LA volume was assessed by echocardiography before and shortly after TAVR (median time: 7\u2009days). Composite rate of death and hospitalization for acutely decompensated heart failure (HF) was recorded and clinical status was assessed through NYHA\u2010class evaluation at 12\u2009months median follow\u2010up. After TAVR, 49 patients (47%) demonstrated a decrease in LA volume. Despite a similar baseline NYHA class, patients with decrease in LA size had significant better improvement in clinical status respect to patients with unvaried LA size (NYHA post: 1.2\u2009\u00b1\u20090.6 vs. 1.8\u2009\u00b1\u20091.1, <jats:italic>p<\/jats:italic> = .001; NYHA reduction: \u22121.6\u2009\u00b1\u20090.9 vs. \u22120.9\u2009\u00b1\u20091.0, <jats:italic>p<\/jats:italic> = .002, respectively). Moreover, these patients had a significantly reduced rate of death or HF\u2010hospitalization (4 vs. 29%, <jats:italic>p<\/jats:italic> = .001) and a significantly longer event\u2010free\u2010survival from Kaplan\u2013Meier curves (<jats:italic>p<\/jats:italic> = .003). COX regression analysis showed that, among echocardiographic parameters, decrease in LA size was an independent predictor of clinical outcome (HR: 0.149, CI: 0.034\u20130.654, <jats:italic>p<\/jats:italic> = .012).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The lack of decrease in LA size shortly after TAVR is associated with significantly higher rates of death and HF\u2010hospitalization, as well as with impaired improvement in clinical status during long\u2010term follow\u2010up.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.28542","type":"journal-article","created":{"date-parts":[[2019,10,21]],"date-time":"2019-10-21T08:31:45Z","timestamp":1571646705000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Short\u2010term decrease of left atrial size predicts clinical outcome in patients with severe aortic stenosis undergoing TAVR"],"prefix":"10.1002","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3622-4965","authenticated-orcid":false,"given":"Roberta","family":"De Rosa","sequence":"first","affiliation":[{"name":"Division of Cardiology, Department of Medicine III Goethe University Hospital Frankfurt  Frankfurt am Main Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1872-2899","authenticated-orcid":false,"given":"Marie\u2010Isabel","family":"Murray","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Medicine III Goethe University Hospital Frankfurt  Frankfurt am Main Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4559-9021","authenticated-orcid":false,"given":"Dietmar","family":"Schranz","sequence":"additional","affiliation":[{"name":"Hessen Pediatric Heart Center Giessen &amp;
