Sudden Death Stratification

Channel Detection to Predict Ventricular Arrhythmia in Patients With Non-ischemic Cardiomyopathy

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.

Inclusion Criteria:

• Adult with NICM
• Previous history of ventricular tachycardia (VT) and no previous history of VT

Exclusion Criteria:

• Inherited cardiomyopathies
• Previous history of myocarditis WITHOUT oedema/scar at the MRI
