To find out the values of strain parameters in the diagnosis and prognosis of arrhythmogenic right ventricular cardiomyopathy (ARVC), 247 patients with initial diagnosis of suspected ARVC were included in this study. Results showed that right ventricular global longitudinal strain (RV GLS) had moderate to high discriminatory power to identify patients with different likelihood of ARVC. Besides, patients with reduced RV GLS had a higher estimated cumulative incidence of combined cardiovascular events. These findings indicate that cardiac magnetic resonance feature tracking could potentially be used as a preferred imaging method in the first visit and follow-up of ARVC.
