Figure 4

Histopathology of myocardium (on day 25 of the illness). There was no finding of the infiltration of the inflammatory cells. The myocardial cell had variation in the size and irregular adhesion, and fibrosis was seen between the muscular fiber. These were not findings of the acute phase but chronic stage, which were delivered by the pressure overload of the right ventricle due to the pulmonary arterial stenosis. Hematoxylin eosin, ×160.
