French Registry of CMR Late Gadolinium Enhancement in Myocarditis

Acute myocarditis is a major cause of death in young adults and carries substantial morbidity, including a significant risk of progression to dilated cardiomyopathy. Current diagnostic and therapeutic strategies remain poorly defined, making risk stratification crucial to enable personalized treatments and reduce mortality and major cardiovascular events.
