Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults with specific types of cardiomyopathy or channelopathies who have an implanted ICD and experience symptoms related to ventricular arrhythmias.
✕Probably not a fit
Patients who are pregnant, breastfeeding, or have a life expectancy of less than 12 months may not benefit from this study.

What this trial studies
This study evaluates the effectiveness of catheter ablation in identifying and eliminating arrhythmogenic substrates to prevent recurrent ventricular arrhythmias and sudden cardiac death in patients with primary cardiomyopathy and/or channelopathies who have an implanted ICD. It is a prospective single-center study conducted at the Arrhythmology Department of San Donato Milanese Hospital. Eligible patients will undergo endo-epicardial electroanatomical 3D mapping and radio-frequency ablation, followed by a structured follow-up schedule to monitor their condition and response to treatment.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the risk of life-threatening arrhythmias and improve survival rates in affected patients.
How similar studies have gone: Other studies have shown promise in using catheter ablation for similar arrhythmogenic conditions, indicating a potential for success in this approach.
