Effectiveness and Safety of Transcatheter Aortic Valve Implantation in Patients With Aortic Stenosis and Variable Ejection Fractions ( 50

We evaluated the safety and efficacy of transcatheter aortic valve implantation (TAVI) in aortic stenosis patients with mid-range ejection fraction (ASmrEF) and compared it to aortic stenosis patients with reduced ejection fraction (ASrEF) and preserved ejection fraction (ASpEF). TAVI cases were stratified by baseline ejection fraction (ASrEF, ASmrEF, ASpEF) and compared for characteristics, procedural outcomes, and change in echocardiographic parameters at 1 year and mortality over a 5-year follow-up. The final study population included 708 patients who underwent TAVI. ASmrEF patients presented with improved EF at 1-year after procedure (49.0 ± 9.8 at 1 year vs 43.0 ± 2.5 at baseline, p
