A RETROSPECTIVE ANALYSIS OF LOW FLOW, LOW GRADIENT SEVERE AORTIC STENOSIS WITH NORMAL EJECTION FRACTION: MORTALITY AND NEED FOR VALVE REPLACEMENT, A SINGLE CENTER STUDY

Abstract

Low flow, low gradient aortic stenosis with normal ejection fraction (LFLGNEF) is considered a seldom-[[Unsupported Character – Codename]]studied entity of the aortic stenosis spectrum (AS). Whether LFLGNEF has a worse prognosis than severe AS remains controversial. We retrospectively identified
