The goal of this study was to determine the functional impact of paradoxical low-gradient aortic stenosis (PLGAS) and clarify whether the relevance of the valvular obstruction is related to baseline flow. Establishing the significance of PLGAS is particularly challenging. Twenty symptomatic patients...
