text: In some, particularly elderly patients, timely surgical aortic valve replacement is not considered because symptoms are mistakenly attributed to comorbid conditions, or the severity of underlying aortic stenosis is underestimated by traditional indices such as aortic valve gradient and peak velocity; this is particularly the case in patients with low-flow, low-gradient with depressed LV ejection fraction but is also true with a recently recognized variant associated with paradoxical low-flow, low-gradient severe aortic stenosis despite normal LV ejection fraction.18–20
