Methods: Anaemic patients (haemoglobin <13.0 g/dL in men and <12.0 g/dL in women) undergoing TAVI and SAVR from the OBSERVANT study were the subjects of this analysis. Results: Preoperative anaemia was an independent predictor of 3-year mortality after either TAVI (HR 1.37, 95% CI 1.12–1.68) and SAVR (HR 1.63, 95% CI 1.37–1.99). Propensity score matching resulted in 302 pairs with similar characteristics. Patients undergoing SAVR had similar 30-d mortality (3.6% versus 3.3%, p = .81) and stroke (1.3% versus 2.0%, p = .53) compared with TAVI. The rates of pacemaker implantation (18.6% versus 3.0%, p  < .001), major vascular damage (5.7% versus 0.4%, p  < .001) and mild-to-severe paravalvular regurgitation (47.4% versus 9.3%, p  < .001) were higher after TAVI, whereas acute kidney injury (50.7% versus 27.9%, p  < .001) and blood transfusion (70.0% versus 38.6%, p  < .001) were more frequent after SAVR. At 3-year, survival was 74.0% after SAVR and 66.3% after TAVI, respectively (p = .065), and freedom from MACCE was 67.6% after SAVR and 58.7% after TAVI, respectively (p = .049). Conclusions: These results suggest that TAVI is not superior to SAVR in patients with anaemia.
