CarDiac MagnEtic Resonance for Primary Prevention Implantable CardioVerter DebrillAtor ThErapy: an International Registry (DERIVATE)

The DERIVATE study was conceived to integrate the information resulted from clinical data, transthoracic echocardiography, and cardiac magnetic resonance (CMR) imaging to provide a more reliable risk stratification in patients affected by heart failure (HF) and worthy of prophylactic implanted cardioverter defibrillator (ICD) therapy. The main purposes of this multicenter registry are to: 1) determine CMR findings, and specifically late gadolinium enhancement (LGE) features, T1 mapping, and extracellular volume (ECV) that predict sudden cardiac death (SCD) and ventricular arrhythmia; 2) provide a comprehensive clinical and imaging score that effectively improves the selection of patients who deserve a prophylactic ICD therapy; 3) evaluate the contribution of machine learning to predict major adverse cardiac events (MACE) as compared to standard clinical scores.
