Key PointsQuestionIs transcatheter aortic valve implantation (TAVI) noninferior to surgical aortic valve replacement (surgery) in patients aged 70 years or older with severe, symptomatic aortic stenosis and moderately increased operative risk?FindingsIn this randomized clinical trial that included 913 patients at moderately increased operative risk due to age or comorbidity, all-cause mortality at 1 year was 4.6% with TAVI vs 6.6% with surgery, a difference that met the prespecified noninferiority margin of 5%.MeaningAmong patients aged 70 years or older with severe, symptomatic aortic stenosis and moderately increased operative risk, treatment with TAVI was noninferior to surgery with respect to all-cause mortality at 1 year.
