Video Summary

The session on phenotypic differences in genotypic arrhythmia cardiomyopathy subcategories highlighted key insights and discussions on diagnosing and managing ACM (Arrhythmogenic Cardiomyopathy) based on genotype-specific features. Dr. Platonov discussed the role of electrocardiographic differences in diagnosing ACM, emphasizing how ECG manifestations can vary across specific genetic subtypes, such as the PKP2, DSC2, and desmoplakin variants. Significant features included T-wave inversion and depolarization abnormalities, with distinct patterns observed between different genotypic subcategories.<br /><br />Dr. Agarwal further explored the use of imaging in diagnosing ACM, showing how advancements in cardiac MRI and CT scans can help detect arrhythmogenic right or left ventricular cardiomyopathies. Imaging plays a crucial role in identifying characteristic patterns like subepicardial delayed enhancement, which aids in differentiating ACM from other conditions such as myocarditis or sarcoidosis.<br /><br />The session also highlighted the impact of exercise on ACM, particularly emphasizing genotype-specific guidelines for exercise in affected individuals. Dr. Cindy James presented evidence linking vigorous exercise to worse outcomes in certain genotypes like PKP2, underscoring the importance of a tailored approach to exercise recommendations based on genetic profiling.<br /><br />Finally, Dr. Julia Cadran-Teregni discussed risk stratification in ACM, illustrating how genetic factors inform risk prediction and management strategies. Various risk calculators have been developed for different genetic subtypes to improve clinical decision-making, emphasizing that a personalized approach, considering both genetic and phenotypic data, enhances the precision of risk assessment in ACM patients.
