Left ventricular outflow tract geometry and dynamics in aortic stenosis : implications for the echocardiographic assessment of aortic valve area

Authors: Pibarot, PhilippeClavel, Marie-Annick
Abstract: Accurate assessment of stenosis severity is crucial for the management of patients with aortic stenosis (AS), and transthoracic echocardiography (TTE) is the primary modality for this purpose. In recent guidelines, the criteria proposed to identify severe stenosis are peak aortic jet velocity $ 4.0 m/sec, mean transvalvular gradient $ 40 mm Hg, aortic valve area (AVA) < 1.0 cm2 . 1,2 However, cardiologists are often confronted with situations in which there are discrepancies among the different echocardiographic parameters of AS severity, and resolving these discrepancies may be challenging.
