Hypereosinophilic Syndrome Leading to Severe Right-Sided Heart Failure in a Patient with Ebstein's Anomaly
Figure 4
(a) Midventricular cross-section of the ventricles, showing a pronounced endocardial thickening of the right ventricle and a tiny right ventricular cavity. On the left side, only mild endocardial thickening and subendocardial fibrosis are evident. RV: right ventricle; LV: left ventricle. (b) Microphotography of the endocardium of the right ventricular septum, with minor calcification and diffuse subendocardial fibrosis.
