Outcome of Patients With Aortic Stenosis, Small Valve Area, and Low-Flow, Low-Gradient Despite Preserved Left Ventricular Ejection Fraction

Objectives The aim of this case match study was to compare the outcome of patients with paradoxical low-flow (left ventricular ejection fraction [LVEF] ≥50% but stroke volume index
