Risk Stratification, Early Prevention and Treatment Strategies for Arrhythmogenic Cardiomyopathy

Definite ACM diagnosis is based on the consensus-based 2010 Task Force Criteria, which include major and minor criteria in six categories (depolarization and repolarization abnormalities, arrhythmia, imaging, histology, and family history/genetics). Among these, repolarization abnormalities (T-wave inversion in the precordial leads) constitute the most commonly observed, followed by frequent premature ventricular complex. With regards to imaging techniques, both the presence of wall motion abnormalities and an abnormal ventricular volume or function are required for fulfilment. Definite ACM consists of two major criteria or one major and two minor criteria or four minor criteria from different categories. Borderline ACM consists of one major and one minor criterion or three minor criteria from different categories.
