Brief summary
The goal of this study is to describe the natural history and clinical events for patients who have Arrhythmogenic Cardiomyopathy with Pathogenic Plakophilin-2 Variants (PKP2-ACM) managed with standard of care.
Detailed description
This is an observational study with both retrospective and prospective data collection. The study is designed to describe the natural history of PKP2-ACM including the signs and symptoms, key clinical events, and impact of the disease on quality of life. A hybrid (retrospective and prospective data collection) approach is being taken with the aim of achieving robust and longitudinal data generation.
