Low-Flow, Low-Gradient Aortic Stenosis With Preserved Left Ventricular Ejection Fraction

Low-flow, low-gradient (LF-LG) aortic stenosis (AS) is characterized by a small aortic valve area (AVA<1.0 cm 2 ), a low gradient (mean <40 mm Hg), and a low-flow state (stroke volume index [SVI] <35 mL/m 2 ). The LF-LG AS…

Low-Flow, Low-Gradient Aortic Stenosis With Reduced Left Ventricular Ejection Fraction

Low-flow, low-gradient (LF-LG) aortic stenosis (AS) with reduced left ventricular ejection fraction (LVEF) occurs in approximately 5% to 10% of patients with AS. This entity is characterized by a small aortic valve area (AVA) compatible with severe AS (i.e., ≤1.0…
