Abstract Introduction: Ultrasound assessment of fetal heart size (FHS) is widely used and recommended in many guidelines of fetal echocardiography due to its clinical value. The aim of this study was an analysis of some fetal heart measurements: ratio of heart area to chest area (HA/ CA) and transversal diameter of heart (AP) and their correlation to gestational age. Material and methods: This retrospective study was based on database of records of ultrasound and echocardiographic examinations performed in our unit and included fetuses between 15th and 39th week of gestation with no evidence of heart defect or any abnormality. Results: 609 ultrasound examinations were analyzed. The mean HA/CA was 0,30 ± 0,015, with no statistical difference between female and male (p>0,05), and seemed to be relatively constant with slight increase with advancing gestational age. The AP diameter in whole group correlated with gestational age (r=0,94) and there was no difference related to the fetuses gender. Conclusion: The correlation of AP diameter and relative constancy of HA/CA ratio with gestational age presented in our normograms could be used for monitoring fetal development, but also for fetal cardiomegaly assessment.

The physiology of the fetal heart differs significantly from that of the mature post-natal organ: e.g., the metabolic supply for adult cardiac contraction relies mainly on fatty acids; whereas, the fetal heart uses carbohydrates as its primary energy source. Limited morphological descriptions of the developing myocardium have appeared. However, additional studies are required to elucidate the ultrastructural changes occuring in the perinatal period when enormous physiological adjustments are made. Although adult animals are most often used in toxocological and pathological analyses, it is also important to investigate fetal cardiac responsiveness to various agents. The vulnerability of the ultrastructure of the fetal mouse myocardium to genetic and environmental assault is the subject of this report. The genetically determined effect on the heart was observed in mouse embryos homozygous for the cab (cardiac abnormality) mutation discovered by Essien.
