Outcomes of Patients With Discordant High-Gradient Aortic Valve Stenosis.

Severe aortic stenosis (AS) is defined by a peak velocity (PV) of ≥4 m/s, a mean pressure gradient (MPG) of ≥40 mm Hg, and an aortic valve area (AVA) of <1.0 cm2 ([1][1]). However, these parameters are often discordant (AVA <1.0 cm2 and MPG <40 mm Hg or AVA ≥1.0 cm2 and MPG ≥
