Background: Some studies suggest that patients with low flow low gradient (LF-LG) aortic stenosis (AS) may achieve worse results after undergoing transcatheter aortic valve implantation (TAVI). Purpose: To compare outcomes between LF-LG AS and high gradient (HG) AS patients submitted to TAVI. Methods: Inclusion of 480 consecutive patients who underwent TAVI between 2008 and 2020 at a single tertiary center. Patients were divided into high gradient AS and LF-LG AS; and baseline characteristics and outcomes after the procedure were collected and compared between groups. Results: Patients with LF-LG AS had worse baseline characteristics, with higher Society of Thoracic Surgeons score (p=0.008), New Euroscore II (p
