Echocardiography (a) and a macroscopic view (b, c) of the heart, and cross section of the coronary artery (d). a Echocardiography showed medial to apical dyskinesia and hypercontractility of the basal segments of the left ventricle, which seemed to have a takotsubo-like appearance. b, c The heart showed a takotsubo-like shape. The epicardium had a reddish color and rough surface. There were no findings of thrombus, embolism or obstruction in the coronary arteries (arrow). d Although there were mild intimal thickening and calcification of the coronary arteries, there was not severe stenosis of them.
