Abstract

Functional mitral regurgitation aetiology affects 1-year mortality after MitraClip implantation, and differences in mortality and hospitalization rates between FMR and DMR can be observed within 2 years. Optimal rMR 1+ was correlated to a more favourable mid-term outcome, particularly in FMR.
