Sudden cardiac death (SCD) risk stratification is a challenge in non-ischemic cardiomyopathy (NICM). The underlying mechanism of monomorphic ventricular tachycardia (VT) is mostly scar related. While electrophysiological mechanisms underlying ventricular arrhythmia are well known, late gadolinium enhanced (LGE) cardiac MRI-3D reconstructions are now able to guide VT ablation procedures. Such exam may help in identifying specific properties of scar at risk of malignant arrhythmia.

Comparison of scar characteristics on cardiac MRI between the two groups.
Detect pro arrhythmogenic scar characteristics
The outcomes will aim to provide scar characteristics from 3D cardiac MRI reconstructions to detect pro arrhythmic properties in NICM patients. Comparisons between NICM patients who experienced VT ablation and NICM patients without history of ventricular arrhythmia will be made. In both groups, Primary outcome will aim to measure the number of the conducting channels into scars (n).
