Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults over 18 years old with a documented diagnosis of sustained ventricular tachycardia and cardiomyopathy who are undergoing or planning to undergo ICD implantation.
✕Probably not a fit
Patients whose ventricular tachycardia is due to a reversible cause may not benefit from this study.

What this trial studies
The END-VT study is a multicenter, prospective, longitudinal cohort study focusing on patients with cardiomyopathy-related ventricular tachycardia (VT). It aims to follow these patients from their first VT event for at least three years to determine the best treatment strategies for maximizing event-free survival. The study will also evaluate the epidemiology of VT, adherence to treatment guidelines, and the safety and effectiveness of current treatment options. Data will be collected through ICD remote monitoring and analyzed by clinical investigators to ensure unbiased results.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment strategies that enhance survival rates and quality of life for patients with ventricular tachycardia and cardiomyopathy.
How similar studies have gone: Other studies have shown success in similar approaches to managing ventricular tachycardia, but this study aims to provide new insights specific to cardiomyopathy patients.
