Arrhythmic risk stratification in patients with left ventricular ring-like scar

Left ventricular (LV) ring-like scar represents the cardiac magnetic resonance expression of different genetic substrates and several clinical scenarios. Arrhythmic risk stratification predictors are still not well understood. In this study, LV ring-like scar exhibits a high rate of ventricular arrhythmias, particularly in the presence of electrocardiogram abnormalities (anterior Q waves and QRS enlargement) together with increased LV volumesOther commonly used risk predictors (such as LV systolic function) did not add significant prognostic information
