Examples of CMR, invasive and CT angiography in two representative patients with Chagas’ heart disease. First patient (top row): a and b CMR reveals transmural LGE pattern in the LV lateral wall (yellow arrow) with concomitant septal midwall LGE (white arrow) and, by invasive angiography, (c and d) normal coronary arteries. Second patient (bottom row): (e) cine-CMR image reveals a classical Chagas’ heart disease finding, the vorticle aneurysm (red arrow), (f and g) LGE reveals subendocardial pattern in the lateral wall (yellow arrow) and, by CT angiography, (h and i) normal coronary arteries. Blue arrow (f and g) indicating the region of interest (ROI) for calculating the mean signal intensity (SI) of the reference normal myocardium
