BACKGROUND: The proven efficacy of transcatheter aortic valve implantation (TAVI) in high-risk patients is leading to the expansion of its indications toward lower-risk patients. However, this shift is not supported by meaningful evidence of its benefit over surgical aortic valve replacement (SAVR). This analysis aims to describe outcomes of TAVI versus SAVR in low-risk patients. METHODS AND RESULTS: We compared the outcome after TAVI and SAVR of low-risk patients (European System for Cardiac Operative Risk Evaluation II [EuroSCORE II] <4%) included in the Observational Study of Effectiveness of SAVR-TAVI Procedures for Severe Aortic Stenosis Treatment (OBSERVANT) study...
