Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals over 16 years old diagnosed with genetic arrhythmogenic cardiomyopathies.

Probably not a fit

Patients with left or biventricular AC carrying specific pathogenic gene variants or those with autoimmune diseases may not benefit from this study.

What this trial studies

This observational study aims to evaluate the effectiveness of a new hybrid PET-MR imaging tool in characterizing tissue and metabolic profiles of patients with arrhythmogenic cardiomyopathies (AC). By enrolling 80 patients with genetic AC, the study will assess the impact of myocardial inflammation on the phenotype and progression of the disease. The research will also explore associated immunological mechanisms and correlate findings with existing anatomical data. This approach seeks to provide a non-invasive method for understanding the disease better and improving patient outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and prognostic tools for patients with arrhythmogenic cardiomyopathies.

How similar studies have gone: While the use of PET-MR imaging in inflammatory conditions has shown promise, this specific application in arrhythmogenic cardiomyopathies is novel and untested.
