High mass (>18g) of late gadolinium enhancement on CMR imaging is associated with major cardiac events on long-term outcome in patients with biopsy-proven extracardiac sarcoidosis.

Background: Cardiac involvement is the most important cause of mortality in patients with systemic sarcoidosis. Late gadolinium enhancement (LGE) on cardiovascular magnetic resonance imaging (CMR) has been shown to be a predictor of major cardiovascular adverse events (MACE) in the setting of systemic sarcoidosis. We sought to evaluate the relationship between LGE mass and adverse long-term outcome in patients with biopsy-proven extracardiac sarcoidosis.
