Diagnosis and management of arrhythmogenic cardiomyopathy: a case report.

Frequently, patients with ACM have more than one mutation in the same gene (compound heterozygosity) or in a second gene (double heterozygosity). Genetic counselling is strongly recommended for family members of the proband. The diagnosis of ACM may be mimicked by other diseases (cardiac sarcoidosis, dilated cardiomyopathy, amyloidosis), thus genetic testing can be useful to determine the presence of the disease. The present report provides an overview of the clinical course, diagnostic criteria, risk stratification, and prognostication for patients with ACM.
