PO-693-06 LATE GADOLINIUM ENHANCEMENT IS A STRONG PREDICTOR OF LIFE-THREATENING ARRHYTHMIAS IN PATIENTS WITH NON-ISCHEMIC DILATED CARDIOMYOPATHY UNDERGOING ICD IMPLANTATION FOR PRIMARY PREVENTION OF SUDDEN CARDIAC DEATH

The usefulness of implantable cardioverter defibrillators (ICD) for primary prevention of arrhythmic sudden cardiac death (SCD) in patients with non-ischemic dilated cardiomyopathy (DCM) has been questioned. Efforts to improve risk stratification have included scores such as the ‘MADIT-ICD benefit score’, and the use of late gadolinium enhancement (LGE) in cardiac magnetic resonance (CMR).
