Abstract

A woman in her 70s developed Takotsubo cardiomyopathy after hospitalization for severe COVID-19 pneumonia. Cardiac MRI showed hypokinesia of the cardiac apex on cine images, high signal intensity on T2-weighted images, and contrast enhancement on late gadolinium enhancement images in the apex. Comparison of early and late phases by resting^99mTc myocardial perfusion imaging showed increased washout of tracer in the apex due to reversible myocardial damage.
