Endocardite valvular em uma bezerra - relato de caso

Abstract

The heart valves are responsible for the separation and closure between the atrioventricular chambers that ensure a continuous and unidirectional blood flow. Any disturbance in these structures compromises cardiovascular functioning. The objective ofthe present study was to report a case of valvular endocarditis in a heifer treated at the University Veterinary Hospital of the Federal University of Alagoas (HVU-UFAL). The animal was 25 days old, was admitted with a complaint of weight loss and loss of appetite.During the 16 days of hospitalization, physical examination and ultrasound were performed. Although antibiotic therapy was instituted, the animal died. At necropsy, it wasfound that the region of the tricuspid valve had a proliferation of yellowish granulomatoustissue that occupied the entire lumen of the artery. Lesions were also observed such as edema in the chest and dewlap region, thickened umbilical stump, large amount of cloudyperitoneal fluid, enlarged liver with rounded edges and appearance of nutmeg when cut, large amount of cloudy fluid in the thoracic cavity, increased fluid in the pericardial sac, darkened kidney, bladder with petechial hemorrhages, enlarged spleen, engorged brain vessels. The diagnosis was concluded through ultrasound, necroscopic and histopathological examinations. It is suggested that a picture of valvular endocarditis thathad an umbilical infection as a probable entry point.
