Is It Only Takotsubo Syndrome? Cardiac MRI and a Case of Delayed ST-Elevation

Abstract

Takotsubo syndrome is a well described clinical phenomenon that often mimics acute coronary syndrome. We present an atypical case of Takotsubo syndrome, characterized by delayed troponin elevation and electrocardiogram changes suggestive of acute coronary syndrome, but a normal coronary angiogram. We describe the integration of cardiac magnetic resonance imaging to identify syndrome overlap, and discuss the utilization of diagnostic modalities beyond coronary angiogram if clinical equipoise exists, including B-type natriuretic peptide/troponin ratio, intravascular coronary imaging, and cardiac magnetic resonance imaging.
