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

Introduction Transcatheter edge-to-edge mitral valve repair using the MitraClip has been widely performed in surgical high-risk patients with reduced left ventricular systolic function and severe functional mitral regurgitation (FMR). Ischaemic heart disease is the leading aetiology of heart disease worldwide. We aimed to assess the clinical implications of ischaemic aetiology in patients with severe FMR who underwent MitraClip implantation.
