AbstractBackground:Although significant efforts have been put into restituting the European bison (Bison bonasus) andincreasing its population, it remains a globally endangered species and requires conservation. Protection programsof bison indicate the need for morphological studies of their individual systems, in order to enhance restitutionprograms and enable appropriate veterinary care. The aim of this study was to investigate the morphology of thecoronary veins of the European bison (Bison bonasus).Results:The study was carried out on 78 hearts of European bison of both sexes, aged 5 to 21 years. Thesubepicardial veins were clearly visible after being filled with dyed synthetic latex (LBS 3060), Plastogen G andBatson’s No. 17. In all the studied animals, the great cardiac vein drains into the coronary sinus. The interventricularparaconal branch and the circumflex branch of the great cardiac vein were distinguished. The left marginal vein,which originated in the apical area or halfway along the length of the left ventricular margin, was easily identifiedin 65 animals (83%). In most animals (51 bison, 65%), the middle cardiac vein drained into the coronary sinus, whilein some animals it drained into the right atrium (27 animals, 35%).Conclusions:Blood from the cardiac walls is drained into the great cardiac vein, the middle cardiac vein, the rightcoronary veins and numerous small cardiac veins.
