Background: Older candidates for transcatheter aortic valve replacement (TAVR) frequently present with both cardiac and noncardiac comorbidities. There are few risk scores that evaluate a wide range of comorbidities. Methods: Patients who underwent TAVR for severe aortic stenosis were retrospectively evaluated. A new prediction model (Cardiac and nonCardiac Comorbidities risk score: 3C score) was determined based on coefficient in the multivariate Cox regression analysis for two-year all-cause mortality. C-statistics were assessed to compare the predictive abilities of the 3C score, the Charlson Comorbidities Index (CCI) score, the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, and the Model for End-stage Liver Disease eXcluding International normalized ratio (MELD-XI) score. Results: The present study included 226 patients (age, 86 ± 5 years; males, 38 %). The values of the CCI score, EuroSCORE II, and MELD-XI score were 2 (1–3), 3.36 (2.12–4.58), and 5.35 (3.05–8.55), respectively. Multivariate Cox regression analysis identified two cardiac (left ventricular ejection fraction [LVEF]
