The Osaka Prognostic Score (OPS), incorporating CRP, albumin, and lymphocyte count, may address this gap. We aimed to evaluate the prognostic value of OPS for predicting in-hospital and one-year all-cause mortality after TAVI. Materials and Methods: In this retrospective single-center cohort study, 244 patients who underwent transfemoral TAVI between December 2022 and January 2024 were analyzed. OPS was calculated at baseline (range: 0\u20133), and its prognostic value for in-hospital and one-year all-cause mortality was evaluated using multivariable Cox regression, ROC analysis, and restricted cubic spline (RCS) modeling. Results: In-hospital and one-year mortality rates were 11.5% and 21.7%, respectively. Higher OPS scores were significantly associated with mortality in both periods. OPS independently predicted in-hospital mortality (HR: 2.018; 95% CI: 1.632\u20132.521; p = 0.017) and one-year mortality (HR: 2.125; 95% CI: 1.300\u20133.473; p = 0.003). ROC analysis yielded AUC values of 0.776 and 0.859 for in-hospital and one-year mortality, respectively. Kaplan\u2013Meier curves revealed significantly reduced survival in patients with higher OPS (log-rank p &lt; 0.001), and RCS analysis demonstrated a significant nonlinear association between increasing OPS values and mortality risk (p &lt; 0.001). Conclusions: OPS is a simple, cost-effective, and biologically relevant prognostic index that independently predicts both in-hospital and one-year mortality following TAVI. By integrating markers of inflammation, nutrition, and immune competence, OPS may offer additional value in risk stratification and support clinical decision-making in this high-risk population.<\/jats:p>","DOI":"10.3390\/medicina61122142","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T12:39:43Z","timestamp":1764679183000},"page":"2142","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Osaka Prognostic Score Predicts In-Hospital and One-Year Mortality Following Transcatheter Aortic Valve Implantation"],"prefix":"10.3390","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1175-3203","authenticated-orcid":false,"given":"Murat","family":"Akdo\u011fan","sequence":"first","affiliation":[{"name":"Department of Cardiology, Ankara Etlik City Hospital, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9854-0554","authenticated-orcid":false,"given":"Emine Cansu","family":"Y\u00fccel","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Etlik City Hospital, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1696-7449","authenticated-orcid":false,"given":"Alperen","family":"Ta\u015f","sequence":"additional","affiliation":[{"name":"Department of Cardiology, K\u0131r\u015fehir Training and Research Hospital, 40080 K\u0131r\u015fehir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3523-8783","authenticated-orcid":false,"given":"Yusuf Bozkurt","family":"\u015eahin","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Etlik City Hospital, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7111-8450","authenticated-orcid":false,"given":"\u00c7a\u011fatay","family":"Tunca","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Etlik City Hospital, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5232-8436","authenticated-orcid":false,"given":"Ahmet","family":"K\u0131vrak","sequence":"additional","affiliation":[{"name":"Department of Cardiology, School of Medicine, Hacettepe University, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7716-6143","authenticated-orcid":false,"given":"K\u00fcr\u015fat","family":"Akbu\u011fa","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Etlik City Hospital, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7193-4324","authenticated-orcid":false,"given":"Veysel Ozan","family":"Tan\u0131k","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Etlik City Hospital, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0139-7962","authenticated-orcid":false,"given":"Ali","family":"Sezgin","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Etlik City Hospital, 06000 Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5429-1323","authenticated-orcid":false,"given":"B\u00fclent","family":"\u00d6zlek","sequence":"additional","affiliation":[{"name":"Department of Cardiology, School of Medicine, Mu\u011fla S\u0131tk\u0131 Ko\u00e7man University, 48999 Mu\u011fla, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1597","DOI":"10.1056\/NEJMoa1008232","article-title":"Transcatheter aortic-valve implantation for aortic stenosis in patients who cannot undergo surgery","volume":"363","author":"Leon","year":"2010","journal-title":"N.
