Use of Percutaneous Mitral Leaflet Approach for Severe Mitral Regurgitation in Cardiogenic Shock: Results From a Multicenter Observational Italian Experience (the Mitra-Shock Study).

Cardiogenic shock (CS) is a medical emergency and a frequent cause of death. CS can be complicated and/or precipitated by mitral regurgitation (MR). The efficacy of percutaneous treatment of MR in patients with cardiogenic shock is unknown. The aims of the study will be to analyse the efficacy of MitraClip therapy on early (30 days) and midterm mortality (6 months) as well as the predictors of outcomes. Investigators will also report the rate of periprocedural complications such as minor and major bleeding, vessel injury and Acute Kidney Injury (AKI).

It is a multicenter retrospective observational study on CE marked medical device (MitraClip® System). Retrospective time range: from 01/01/2012 to 01/01/2020
