ABSTRACT:
A congenital heart malformation was diagnosed in a free-ranging adult female European brown bear (Ursus arctos) found dead due to intraspecific violence. At necropsy, the heart had all four features of Fallots tetralogy. No further malformations were identified in the animal, which was of normal size and weight for its age, in normal body condition, and had probably borne young. The heart condition was considered to have contributed to death during an attack by another bear.
Key words: Congenital, European brown bear, Fallots tetralogy, heart malformation, intraspecific, pathology, Ursus arctos.
