  • Cumulative incidence rates are shown for the whole population of 435 patients with low gradient severe aortic stenosis (MPG ≤40 mm  Hg, AVA<1.0 cm2, EF≥55%) and for the subgroups of patients with a VR<0.25 and a VR≥0.25 together with the p value according to the χ2 test.

  • AVA, aortic valve area; MPG, mean pressure gradient; VR, velocity ratio.
