Abstract
Sudden cardiac death (SCD) is a major health problem worldwide. The majority of cases are due to ventricular tachycardia (VT) or ventricular fibrillation (VF). The left ventricular ejection fraction (LVEF) has been adopted as a criterion for the risk stratification of patients at risk of SCD and for the prescription of implantable cardioverter defibrillator (ICD) therapy. However, most patients succumbing to SCD fall outside current indications for primary prevention ICD implantation and most ICD recipients do not receive therapy from the device. Cardiovascular magnetic resonance (CMR), the gold standard for the characterization of myocardial phenotypes, can identify myocardial scar, a substrate of ventricular arrhythmias. This review focuses on how CMR can contribute to the arrhythmic risk stratification and how it may help in selecting patients for an ICD.
