Comparison of circulating miRNA among control subjects, definite ARVC patients, borderline or possible ARVC patients, and idiopathic VT patients. Graph depicts fold change of miRNAs in each group as compared to control. *P < 0.05, **P < 0.01, ***P < 0.001. ARVC, arrhythmogenic right ventricular cardiomyopathy; miRNA, microRNA; VT, ventricular tachycardia.
