Midventricular Takotsubo Cardiomyopathy Following COVID-19 Infection: Diagnostic Role of Cardiac Magnetic Resonance Tissue Mapping
Takotsubo cardiomyopathy is typically characterized by reversible apical left ventricular (LV) akinesis, while atypical phenotypes involve the mid or basal segments. We describe the case of a 49-year-old woman with viral gastroenteritis and decompensated heart failure. Following normal coronary angiogram, an echocardiogram showed severe LV hypokinesis with circumferential dyskinesis in the midsegments consistent with atypical Takotsubo cardiomyopathy. Subsequent cardiac magnetic resonance (CMR) imaging revealed markedly improved LV function with diffuse myocardial edema in the mid and apical segments on tissue characterization.
