Identifying and treating heart rhythm issues in patients with specific heart conditions

Arrhythmogenic Substrate Assessment in Patients With Primary Cardiomyopathies and/or Channellopaties With and Without History of Brugada Syndrome: A Prospective Follow-up Study

Not applicable Interventional IRCCS Policlinico S. Donato · NCT03304847

This study is testing if a procedure called catheter ablation can help people with certain heart conditions and implanted devices by fixing heart rhythm problems to prevent serious issues like sudden cardiac death.

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.

Who should consider this trial

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.

Not a fit: Patients who are pregnant, breastfeeding, or have a life expectancy of less than 12 months may not benefit from this study.

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 performed: Other studies have shown promise in using catheter ablation for similar arrhythmogenic conditions, indicating a potential for success in this approach.
