There are no studies comparing MitraClip and optimal medical therapy (OMT) in patients with advanced heart failure (HF).~The aim of this study is to assess the effects of MitraClip on health status, measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ), in patients with secondary mitral regurgitation (SMR) and advanced HF.~Secondary aims are to evaluate persistence of such benefits up to 1 year as well as changes in survival, HF hospitalization, functional status, symptoms, echocardiographic parameters, and further optimization in medical therapies.~MITRADVANCE-HF is a prospective, randomized, parallel-controlled, open-label, multicenter study trial enrolling patients with SMR and advanced HF on maximally tolerated standard of care therapies for HF according to the most recent guidelines. Enrolled patients will be randomly assigned, in a 1:1 ratio, to a device arm consisting of MitraClip therapy added to optimal medical therapy (OMT) or a control arm of OMT alone. Primary end-point was the absolute change in overall KCCQ summary score (KCCQ-OS) from baseline to 3 months follow-up. A total of 172 patients should be recruited (86 in the device arm and 86 in the control arm. Approximately 20 Italian centers are involved. All screened patients need to be approved by an eligibility committee before randomization. Visit 0 will be performed before randomization. A discharge visit will be performed in patients randomized to the device arm. Visit 1, 2 and 3 will be performed at 3, 6 and 12 months after the randomization in both arms. Transthoracic echocardiography performed during Visit 0, 1, 2 and 3 will be collected and analyzed by an independent Core Laboratory. Adverse events will be adjudicated by an independent committee. Enrolment duration will be of 24 months. The primary completion is the date when the last enrolled subject is assessed for the collection of the primary endpoint. The end of the study is when the last enrolled subject has completed the last follow-up visit.
