Takotsubo syndrome or acute myocarditis? The role of cardiac magnetic resonance imaging

Acute myocarditis is often misdiagnosed, and its evolution is not always benign; correct and prompt diagnosis is therefore essential.We report the case of a 62-year-old woman with chest pain after a stressful event and ST-segment elevation on the electrocardiogram, in whom urgent cardiac catheteriza...
