Although numerous clinical, echocardiographic, and hemodynamic risk factors have been identified, accurately predicting eaRHF remains challenging. Cardiac magnetic resonance (CMR) provides a precise, non-invasive evaluation of cardiac structure and function and may enhance risk stratification eaRHF. This study aims to assess the predictive value of preoperative CMR-derived parameters, comparing their utility to established echocardiographic and right heart catheterization (RHC) markers for identifying eaRHF.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This retrospective analysis was conducted on 55 patients who received CMR before LVAD implantation at our center between 2018 and 2024. Of these 55 patients, 40 had image quality sufficient for offline analysis. Patients receiving a temporary right ventricular assist device (tRVAD) intraoperatively were defined as having eaRHF. Receiver Operating Characteristic (ROC) analysis was used to evaluate the predictive capability of CMR, echocardiographic, and RHC parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ten patients (25%) developed eaRHF. Preoperative bilirubin levels were significantly higher in the eaRHF group (1.6\u2005mg\/dl vs. 1.1\u2005mg\/dl, <jats:italic>p<\/jats:italic>\u2009=\u20090.010). Echocardiographic Tricuspid Annular Plane Systolic Excursion (TAPSE) tended to be lower in eaRHF patients (12\u2005mm vs. 18\u2005mm, <jats:italic>p<\/jats:italic>\u2009=\u20090.080). RHC parameters, specifically right ventricular stroke work index (RV-SWI; <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.001), cardiac output (CO; <jats:italic>p<\/jats:italic>\u2009=\u20090.003), and cardiac index (CI; <jats:italic>p<\/jats:italic>\u2009=\u20090.004), were significantly lower in eaRHF patients. CMR showed significantly higher RV end-diastolic volumes (RV-EDV, 288.4\u2005ml vs. 216.7\u2005ml, <jats:italic>p<\/jats:italic>\u2009=\u20090.046) and indexed RV-EDV (RV-EDVi, 135.4\u2005ml\/m<jats:sup>2<\/jats:sup> vs. 104.7\u2005ml\/m<jats:sup>2<\/jats:sup>, <jats:italic>p<\/jats:italic>\u2009=\u20090.033) in the eaRHF group.
