Predictors of mortality in ischaemic versus non-ischaemic functional mitral regurgitation after successful transcatheter mitral valve repair using MitraClip: results from two high-volume centres.

Despite the similar survival between ischaemic and non-ischaemic FMR, different predictors of all-cause mortality were demonstrated. Further clinical studies are mandated to focus on each FMR subgroup with stratification by ischaemic origin.
