WebWhat is Aortic Stenosis? Aortic stenosis is defined as a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium. The increased pressure load imposed by aortic stenosis results in compensatory hypertrophy of the left ventricle (LV). WebMay 14, 2024 · Abstract. Paradoxical low-flow aortic valve stenosis is defined as the presence of small valve area (c/w severe Aortic stenosis), low transvalvular gradients (non -severe range) in the presence of low transvalvular flow, but with normal ejection fraction (>50%). This discordant echocardiographic data creates doubts about the severity of the ...
