Abstract
(3+/4+), 8 had mild MR (2+/4+), 20 had trivial MR (1+/4+), and 4 had no MR. Moreover, both EROA (24.4±11.5 vs. 11.2±10.3 mm, Pb.001) and MR index (1.9±0.3 vs 1.3±0.7, Pb.001) showed a significant reduction independent from etiology of MR. Improvement in MR was directly correlated, by means of linear regression, with mean transaortic gradient reduction (Pb.01) but not with the increase in LVEF (P=.08). Subgroups analysis showed a significant reduction in the Edward Sapien group but not in the CoreValve group. Conclusion: MR significantly improves after TAVI. This result is independent from the etiology of the mitral disease and correlates with transaortic gradient reduction.
