In apparently asymptomatic severe aortic stenosis (AS) group, stress echocardiography objectively identifies symptomatic, high-risk AS patients requiring early aortic valve replacement (AVR). The low-flow, low-gradient AS is well-characterized clinical entity with distinct diagnostic, management, and clinical outcome challenges. A comprehensive two-dimensional transthoracic echocardiography (2D echo) and Doppler and low-dose dobutamine stress echocardiography are of paramount importance for accurate diagnosis and timely decision of AVR. However, clinicians and imaging experts should be aware of the pitfalls and inaccuracies inherent in 2D echo/Doppler measurements and the effects of pathophysiological factors which impact the stroke volume and transvalvular gradient measurements. In appropriate clinical situations, clinicians should take additional help of cardiac computational tomography, cardiac magnetic resonance imaging, and biomarkers.
