Commentary: Searching for simpler parameters in the context of non-ischemic dilated cardiomyopathy

Secondary functional mitral regurgitation (FMR) in patients with non-ischemic dilated cardiomyopathy (NIDCM) is associated with worse prognosis and poor survival,1 and results after mitral valve (MV) surgery are still controversial. The main reason is that FMR is not an intrinsic disease of the valve, but instead it mirrors a ventricular disease. In NIDCM, progressive left ventricular (LV) remodeling causes papillary muscle displacement and mitral annular dilation. Both conditions cause leaflet tethering and reduce leaflet coaptation.
