Midwall Fibrosis: Cardiac Magnetic Resonance Imaging in Risk Stratifying Cardiomyopathies

The United Kingdom’s National Institute for Health and Care Excellence guidance on implantable cardiac defibrillator (ICD) therapy recommend ICD in those with left ventricular dysfunction and a high risk of sudden cardiac death (SCD). SCD accounts for 30% deaths in non-ischaemic dilated cardiomyopathy (DCM), however risk stratifying and predicting SCD in DCM is a major management challenge. We present two cases demonstrating the potential role of cardiac magnetic resonance imaging in risk stratifying DCM.
