Abstract

Typological differentiation of coronary arteries binds to various areas of vascularisation, which could suggest essential differences between vasculatory dimensions. There are not many papers analysing the influence of heart vascularisation on epicardial vessel dimensions during postnatal human life, furthermore, there are hardly any papers dealing with the prenatal period.
The subject of examination was 188 human foetuses from 4th to 7th month of prenatal life. Foetuses were fixed for minimum 3 months in 9% formalin solution. They were taken from natural abortions and did not characterise any external malformations. There was a different number of foetuses in a variety of morphological age groups. Adachi classification was used to describe all types: type I - classical, with equal coronary arteries, type II - predominance of right coronary artery, type III - predominance of left coronary artery.
Speed of circumflex branch growth in different types of vascularisation is various. Analysis of the differences among dimensions of artery in various types showed there are statistically crucial ones, especially between: types III and I or types III and II.
