Preoperative left atrial diameter index (LADI) was measured, and patients were classified as normal (&lt;2.3\u2009cm\/m2) or abnormal (\u22652.3\u2009cm\/m2). Clinical, operative, and postoperative outcomes were compared. The primary endpoint was 30-day all-cause mortality; secondary endpoints included postoperative atrial fibrillation (POAF), neurological events, renal impairment, re-exploration for bleeding, and intraoperative pacing wire requirement.<\/jats:p>\n                  <jats:p>Nearly half of patients (48.8%) had abnormal LADI. Patients with enlarged atria were more often female, had smaller body size, and were significantly more likely to undergo MVR (42.7% versus 18.1%, p\u2009&lt;\u20090.001). Abnormal LADI was strongly associated with POAF (16.0% versus 7.4%, p\u2009=\u20090.006) and intraoperative pacing wire insertion (38.3% versus 23.5%, p\u2009=\u20090.001). Multivariate analysis confirmed severe LADI as an independent predictor of POAF (OR 3.91, p\u2009=\u20090.001) and pacing requirements (OR 2.31, p\u2009=\u20090.004). No significant differences were observed in 30-day mortality, stroke\/transient ischemic attack, renal dysfunction, or bleeding complications.<\/jats:p>\n                  <jats:p>Preoperative LADI is an independent predictor of postoperative arrhythmic complications and pacing needs after valve replacement, but not early mortality. Incorporating LADI into preoperative risk assessment may improve rhythm surveillance and perioperative planning. Future prospective studies should evaluate its long-term prognostic value and role in reverse remodeling after surgery.<\/jats:p>","DOI":"10.1055\/a-2828-9823","type":"journal-article","created":{"date-parts":[[2026,3,21]],"date-time":"2026-03-21T01:18:36Z","timestamp":1774055916000},"page":"477-484","source":"Crossref","is-referenced-by-count":0,"title":["Beyond the Chamber: Left Atrial Diameter Index Shapes Outcome in Valve Surgery"],"prefix":"10.1055","volume":"74","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4676-8942","authenticated-orcid":false,"given":"Nizar R.","family":"Alwaqfi","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Department of General Surgery, Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rana B.","family":"Altawalbeh","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Majd M.","family":"AlBarakat","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zina","family":"Alwaqfi","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Universit\u00e9 Paris Cit\u00e9, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdullah","family":"Almomani","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amjed","family":"Abdel Al","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, Mayo Clinic, Arizona, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haya","family":"Alsheqerat","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manaf","family":"Alibraheem","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9738-2575","authenticated-orcid":false,"given":"Khalid Shaker","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Department of General Surgery, Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qusai","family":"Aljarrah","sequence":"additional","affiliation":[{"name":"Division of Vascular Surgery, Department of General Surgery, Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2026,3,20]]},"reference":[{"issue":"05","key":"ref1","doi-asserted-by":"crossref","first-page":"467","DOI":"10.4065\/76.5.467","article-title":"Left atrial volume: Important risk marker of incident atrial fibrillation in 1655 older men and women","volume":"76","author":"T SM Tsang","year":"2001","journal-title":"Mayo Clin Proc"},{"issue":"12","key":"ref2","doi-asserted-by":"crossref","first-page":"2357","DOI":"10.1016\/j.jacc.2006.02.048","article-title":"Left atrial size: Physiologic determinants and clinical applications","volume":"47","author":"W P Abhayaratna","year":"2006","journal-title":"J Am Coll Cardiol"},{"issue":"12","key":"ref3","doi-asserted-by":"crossref","first-page":"1284","DOI":"10.1016\/S0002-9149(02)02864-3","article-title":"Left atrial volume as a morphophysiologic expression of left ventricular diastolic dysfunction and relation to cardiovascular risk burden","volume":"90","author":"T SM Tsang","year":"2002","journal-title":"Am J Cardiol"},{"issue":"02","key":"ref4","doi-asserted-by":"crossref","first-page":"327","DOI":"10.1016\/j.jacc.2004.03.062","article-title":"Long-term prognostic significance of left atrial volume in acute myocardial infarction","volume":"44","author":"R Beinart","year":"2004","journal-title":"J Am Coll Cardiol"},{"issue":"04","key":"ref5","doi-asserted-by":"crossref","first-page":"835","DOI":"10.1161\/01.CIR.92.4.835","article-title":"Left atrial size and the risk of stroke and death.
