Despite advances in surgical management, in-hospital mortality remains substantial, and early, reliable risk stratification tools are urgently needed. We targeted to assess the relationship between the De Ritis ratio (DRr) and in-hospital mortality in patients experiencing surgery for AAD. Methods: In this single-center retrospective study, 182 patients who underwent surgery for AAD between 2020 and 2025 were included. Demographic, clinical, laboratory, and echocardiographic data were analyzed. Receiver operating characteristic analysis was used to estimate the DRr\u2019s discriminatory ability, and univariable and multivariable logistic regression analyses were utilized to find predictors of in-hospital mortality. Results: In-hospital mortality occurred in 59 patients (32.4%). When comparing survivors to non-survivors, the DRr was noticeably greater. Along with age, lactate level, and ejection fraction, the DRr continued to be an independent predictor of in-hospital mortality in multivariable analysis. Receiver operating characteristic analysis showed moderate discriminatory performance of the DRr, with an area under the curve of 0.701 and an optimal cut-off value of 1.308. Conclusions: The DRr is a practical and accessible biomarker related to in-hospital mortality in surgically treated AAD and may provide incremental prognostic value when used alongside established clinical and laboratory parameters.<\/jats:p>","DOI":"10.3390\/jcm15093419","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T15:01:18Z","timestamp":1777474878000},"page":"3419","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["De Ritis Ratio as an Independent Predictor of In-Hospital Mortality in Surgically Treated Acute Aortic Dissection"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2684-7256","authenticated-orcid":false,"given":"Kemal E\u015fref","family":"Erdo\u011fan","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Ankara Yildirim Beyazit University, School of Medicine and Ankara Bilkent City Hospital, 06760 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Burak","family":"Karde\u015fler","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Bilkent City Hospital, 06800 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0744-0001","authenticated-orcid":false,"given":"Muhammet Fethi","family":"Sa\u011flam","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Ankara Yildirim Beyazit University, School of Medicine and Ankara Bilkent City Hospital, 06760 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2758-7644","authenticated-orcid":false,"given":"Emrah","family":"U\u011fuz","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Ankara Yildirim Beyazit University, School of Medicine and Ankara Bilkent City Hospital, 06760 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9182-0690","authenticated-orcid":false,"given":"Murat","family":"Y\u00fccel","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Ankara Bilkent City Hospital, 06800 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6877-9730","authenticated-orcid":false,"given":"Servet","family":"Turgut","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Kars Harakani State Hospital, 36100 Kars, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehmet Murat","family":"Yi\u011fitba\u015f\u0131","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Yildirim Beyazit University, School of Medicine and Ankara Bilkent City Hospital, 06760 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2747-3823","authenticated-orcid":false,"given":"Mehmet","family":"Erdo\u011fan","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Yildirim Beyazit University, School of Medicine and Ankara Bilkent City Hospital, 06760 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6204-316X","authenticated-orcid":false,"given":"Kamuran","family":"Kalkan","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Yildirim Beyazit University, School of Medicine and Ankara Bilkent City Hospital, 06760 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erol","family":"\u015eener","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Ankara Yildirim Beyazit University, School of Medicine and Ankara Bilkent City Hospital, 06760 Ankara, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"ref_1","first-page":"e78231","article-title":"From Cardiac Arrest to Survival: Managing Acute Type A Aortic Dissection With Emergent Surgery","volume":"17","author":"Leivaditis","year":"2025","journal-title":"Cureus"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"44307","DOI":"10.31083\/RCM44307","article-title":"A Comprehensive Review of Acute Type A Aortic Dissection: Epidemiology, Classification, Management Strategies, Mortality Risk Assessment, and Ethical Considerations for Patients who Refuse Blood Transfusions","volume":"26","author":"Belyaev","year":"2025","journal-title":"Rev.
