Representative photomicrographs of H&E stained longitudinal sections of maternal heart from different groups. Normal histological structure of heart from SV (a) and SE (b) groups. Maternal heart from RV group (c-h) showing irregular myocardial fibers (c), widened gaps between fibers with macrophage (arrow, d), necrotic foci (asterisk, e-g), cell mobilization from rippled muscle fibers (arrowhead, f&g), hemorrhage (h) within degenerated myofibrils (h). Improved heart structure after edaravone injection in the RE group (i). h; hemorrhage, MF; myocardial fibers, MG; myocardial gap, MN; myocardial nuclei
