Sudden cardiac death (SCD) still represents the most challenging and controversial issue in cardiology. Even though implementation of implantable cardioverter-defibrillators in high-risk patients is effective in reducing SCD, the occurrence of life-threatening arrhythmias in the general population is disproportionately high as an expression of latent cardiac disease. Substrate myocardial analysis seems to be of pivotal importance to detect anatomic abnormalities underlying clinical conditions predisposing to major arrhythmic events. High-density electroanatomic mapping may be considered an effective technique to identify myocardial substrate abnormalities and to improve the identification of markers of increased arrhythmic risk in patients with ventricular arrhythmic disorders.
