Prognostic CMR predictors of adverse outcomes in patients with suspected ARVC

Background ARVC is one of the commonest causes of sudden cardiac death amongst people younger than 30 years. Establishing the diagnosis still remains a difficult task, since there is as yet no single non-invasive gold standard test to confirm it. It is therefore essential to identify within a population with suspected ARVC, a subset who will indeed be at a higher risk of developing the disease, and thus at a higher risk of MACE. Imaging criteria that are most commonly studied include right ventricular volumes, ejection fraction and regional wall motion abnormalities. We sought to determine which imaging parameters were better predictors of worse clinical outcomes.
