Abstract

Background: The relationship between the reduction in aortic valve pressure gradient (AVG) after transcatheter aortic valve implantation (TAVI) and improvements in left ventricular ejection fraction (LVEF) or long-term survival remains unclear. Methods and Results: We retrospectively analyzed 121 patients with aortic stenosis (AS) and LVEF
