Background/Aim. Myocardial bridges (MB) are narrower or wider fascicles of the atrial or ventricular muscle fibres which form a “bridge” either across the coronary arteries’ main trunks or their major subepicardial branches. The aim of this research was to determine and present the exact frequency, morphological, morphometric and histological characteristics of MB in the level of anterior interventricular branch (AIB) in human fetal hearts. Methods. The study was performed on 63 human fetal hearts. Images of the analyzed hearts were captured with digital camera and afterwards morphometrically evaluated with ImageJ. Characteristic cases of the MB were dissected, sampled and further routinely processed for the subsequent histological analysis. Finally, obtained morphometric data were statistically analyzed. Results. Myocardial bridges were found in 53.97% of the hearts. Percentage of the hearts with only one MB detected on AIB (88.24%) was significantly higher than the percentage of the hearts with two MBs on AIB (11.76%) (p < 0.001). Presence of MB on the AIB was proven histologically and under the magnifying glass. Conclusion. We suggest that MBs are just one anatomical variation of the fetal period, as well as of adulthood.
