The outcome of aortic valve replacement for patients with low gradient severe aortic stenosis and preserved ejection fraction is debated. The aim of the current study was to evaluate the effect of aortic valve intervention on survival in that group. The findings suggest that aortic valve intervention is associated with improved survival among patients with low gradient severe aortic stenosis and preserved left ventricle function. The presence of either a low or normal stroke volume index did not affect the mortality benefit.
