✅   The Impact of Concomitant Mitral Regurgitation on Echocardiography Parameters After TransCatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis

tech

CONCLUSIONS: These findings suggest that patients with moderate-to-severe baseline MR before TAVR showed greater pronounced improvements in specific echocardiographic parameters related to LV function and geometry, particularly in LVEF, LVEDV index, LVESV index, and LVESD, compared to those with none-to-mild MR. Future studies should focus on stratifying outcomes according to MR etiology and using advanced imaging techniques to delineate better the mechanisms underlying these improvements.
