Postoperative Reverse Remodeling and Symptomatic Improvement in Normal-Flow Low-Gradient Aortic Stenosis After Aortic Valve Replacement

Severe aortic stenosis (AS) most often presents with reduced aortic valve area (<1 cm 2), normal stroke volume index (≥35 mL/m 2), and either high mean gradient (≥40 mm Hg; normal-flow high-gradient ...

Low-Flow, Low-Gradient Severe Aortic Stenosis Despite Normal Ejection Fraction Is Associated With Severe Left Ventricular Dysfunction as Assessed by Speckle-Tracking ...

Low-flow low-gradient (LFLG) is sometimes observed in severe aortic stenosis (AS) despite normal ejection fraction, but its frequency and mechanisms are still debated. We aimed to describe the ...
