Management of aortic valve replacement according to the gradient across symptomatic aortic valve stenosis and its prognostic impact
Abstract
Treatment strategy for low‐gradient (LG) aortic stenosis (AS) remains an unresolved issue. The presence of a low aortic gradient and preserved left ventricular ejection fraction (LVEF) might lead toward the underestimation of aortic stenosis severity and a more conservative management. We sought (a) to describe the nature and timing of intervention according to flow/gradient subgroups in patibents with LG‐AS, (2) to determine the factors associated with the decision to intervene, and (c) to describe prognosis.
