This cluster of papers focuses on the diagnosis, management, and genetic aspects of Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) in athletes and young adults. It explores the role of exercise in triggering sudden cardiac death, recommendations for preparticipation screening, interpretation of electrocardiograms in athletes, and the use of implantable cardioverter-defibrillator therapy. Additionally, it discusses the impact of exercise on cardiac remodeling, the association with atrial fibrillation, and the genetic mutations associated with ARVC.
