Coronary artery disease is the most frequent cause of SCD in individuals over the age of 30, while hypertrophic cardiomyopathy in those below 30 years of age. Cardiac magnetic resonance (CMR), a noninvasive, non-radiating technique, can reliably perform evaluation of 1) cardiac function through assessment of ventricular volumes and ejection fraction and 2) tissue characterization through oedema, fat and fibrotic substrate assessment. The presence of scar has been linked to ventricular arrhythmias, which is believed to be the major cause of SCD in both ischemic and nonischemic cardiomyopathy.
The extent of late gadolinium enhancement (LGE) in hypertrophic cardiomyopathy is correlated with risk factors of SCD. In idiopathic dilated cardiomyopathy, the presence of midwall fibrosis, assessed by CMR, also predicts SCD. In coronary artery disease, infarct size is the strongest predi.. View More»
