Arrhythmogenic right ventricular cardiomyopathy

The authors aim to review the evolving understanding of arrhythmogenic cardiomyopathy (ACM), particularly focusing on the shift from a phenotype-first to a genotype-first approach in its diagnosis and management. They highlight the implications of this transition for identifying and treating patients at risk of sudden cardiac death due to ventricular arrhythmias, especially among young individuals and endurance athletes.
