Arrhythmogenic Right Ventricular Cardiomyopathy in Monozygotic Twins—A Case Report

ABSTRACT Arrhythmogenic right ventricular cardiomyopathy (ARVC) is the classic phenotype of arrhythmogenic cardiomyopathy. ARVC in twins have been reported rarely. Herein, we report an unusual case of young monozygotic twins with early disease onset presenting different course of disease progression and clinical manifestations. Echocardiography with multiparameters was used for the diagnosis, screening, and follow‐up of the disease for the family. Cardiac magnetic resonance revealed the fibrosis distribution in the right ventricular with late gadolinium enhancement. DSG2 mutation was found in the family members, which confirmed the final diagnosis of ARVC.
