ABSTRACT
Purpose - To develop a siereological comparision between right (RV) and left ventricle (LV) myocardium during the third human gestacional trimester. Methods - Five human fetal hearts of the third trimester provided representative samples of 5 RV myocardium and 4 LV myocardium. The material was fixed in 10 per cent buffered formaldehyde, and processed through riutine methods. Fifteen microscopic fields were randomly hosen and counted in each ventricular myocardium using an "M-42" test system. The following stereological parameters were assessed Vv (per cent), Lv (mum2), Sv (mum2/mum3), VP (mum3), Nv (1/mm3) and total N. Results - No sibginifant difference between the stereological parameters of the myocardial structures assessed was evidenced, when comparing RV and LV. Conclusion - Right and left human ventricular myocardium are very similar during the fetal period least in regard to their structural aspects.
