The aim of the present work was to determine vascularisation varieties of diaphragmatic heart surface which would be useful in cardiology and cardiosurgery, in particular. The methods used in the present study included morphological investigations (direct preparations) and clinical examinations (coronarography). The study was performed on posterior coronary vessels of 163 human hearts aged 28-88. Ninety-one of these heats were analysed on the basis of intra vitam angiography. Three coronary vascularisation varieties of posterior heart surface were distinguished and the criteria of their determination in selective coronarography were postulated. Both research methods revealed that the right variety of coronary vascularisation occurred most often, while left variety was the least frequent. Symmetric variety which is optimal from the point of view of myocardial haemodynamics was found in 0.25% cases. The frequency of the right and symmetric varieties observed in the studies following both methods are comparable. In the case of left variety, the interpretation of blood supply to posterior surface on the basis of coronarography is much more difficult when compared with the remaining varieties. Coronarography may often be insufficient to determine the range of vascularisation of particular coronary arteries.
