LV strain value is markedly reduced in patients with CP and LVpEF. Lower preoperative epicardial CS value is associated with greater risk of early refractory hypotension and more aggressive fluid management.

Despite a higher risk profile in FMR patients, the short-term and 1-year outcomes were not significantly different. We conclude that MC therapy is similar between FMR and DMR patients until 1-year follow-up. Large randomized trials are warranted to fully and further assess the clinical impact of the procedure in these two MR etiologies over a longer period of time.
