Schematic representation of a potential risk-stratification and ICD selection strategy based on LGE. Additional factors may have variable prognostic weight in different sub-population of LGE + DCM patients. Risk factors for non-sudden death, such as Age, NYHA class and comorbidities will also influence ICD benefit. LGE: late gadolinium enhancement. VA: ventricular arrhythmias. SD: sudden death. ICD: Implantable cardioverter defibrillator. LVEF: left ventricular ejection fraction. ECV: extracellular volume fraction. NSVT: non sustained ventricular tachycardia. * LGE− patients with very severe LV dysfunction (LVEF ≤ 20%) have been suggested to have higher risk of VA/SD; however, these patients might have a not negligible competing risk of non-sudden death with a direct impact on the potential benefit of primary prevention ICD.
