We validated this score in patients receiving transcatheter aortic valve replacement (TAVR) and aimed to generate further risk discrimination by adding invasive hemodynamics parameters. Methods: Patients who underwent TAVR at our institute between 2015 and 2020 were included and followed for 2 years from index discharge. Patients were randomly assigned to the derivation cohort or the validation cohort. In the derivation cohort, the original SHFM score was modified by adding baseline hemodynamics parameters to evaluate the primary outcomes: 2-year incidence of mortality or readmission from heart failure. The model performance of the modified SHFM score was evaluated in the validation cohort. Results: A total of 217 patients (median age: 86 (83, 88) years old, 64 (29%) men) were included. From the derivation cohort (N = 108), a novel modified SHFM score was constructed: 6 \u00d7 (original SHFM score &lt; 88.1%) + 5 \u00d7 (pulmonary capillary wedge pressure &gt; 14 mmHg) + 4 \u00d7 (cardiac index &lt; 2.26 L\/min\/m2), which had an improved discrimination compared with the original model (area under the curve: 0.887 vs. 0.679, p = 0.014). In the validation cohort (N = 109), the modified SHFM score showed accurate predictive discrimination of the 2-year cumulative incidence of the primary endpoint into three groups (a low score group with 0\u20135 points, 3%; an intermediate score group with 6\u201310 points, 12%; and a high score group with 11\u201315 points, 43%, p &lt; 0.001). Conclusion: A modified SHFM score consisting of the original SHFM score and invasive hemodynamics parameters predicted mortality and morbidity following TAVR. Evaluation of the external validity of this score in other cohorts needs further investigation.<\/jats:p>","DOI":"10.3390\/jcm10245807","type":"journal-article","created":{"date-parts":[[2021,12,13]],"date-time":"2021-12-13T01:28:11Z","timestamp":1639358891000},"page":"5807","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prognostic Implications of a Modified Seattle Heart Failure Model Score Following Transcatheter Aortic Valve Replacement"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7294-7637","authenticated-orcid":false,"given":"Teruhiko","family":"Imamura","sequence":"first","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikhil","family":"Narang","sequence":"additional","affiliation":[{"name":"Advocate Christ Medical Center, Oak Lawn, IL 60453, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Onoda","sequence":"additional","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7551-3431","authenticated-orcid":false,"given":"Shuhei","family":"Tanaka","sequence":"additional","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuichi","family":"Ushijima","sequence":"additional","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsuo","family":"Sobajima","sequence":"additional","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuyuki","family":"Fukuda","sequence":"additional","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9747-2511","authenticated-orcid":false,"given":"Hiroshi","family":"Ueno","sequence":"additional","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koichiro","family":"Kinugawa","sequence":"additional","affiliation":[{"name":"The Second Department of Internal Medicine, University of Toyama, Toyama 9300194, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1609","DOI":"10.1056\/NEJMoa1514616","article-title":"Transcatheter or Surgical Aortic-Valve Replacement in Intermediate-Risk Patients","volume":"374","author":"Leon","year":"2016","journal-title":"N.
