Outcome of Normal‐Flow Low‐Gradient Severe Aortic Stenosis With Preserved Left Ventricular Ejection Fraction: A Propensity‐Matched Study

Outcome of Normal‐Flow Low‐Gradient Severe Aortic Stenosis With Preserved Left Ventricular Ejection Fraction: A Propensity‐Matched Study

Background Normal‐flow, low‐gradient severe aortic stenosis (NF‐LG‐SAS), defined by aortic valve area <1 cm2, mean gradient <40 mm Hg, and indexed stroke volume >35 mL/m2, is the most prevalent form of low‐gradient aortic stenosis (AS). However, the true severity of AS and the management of...
