Left Atrioventricular (AV) Thrombosis and a Compacted Fracture of Lumber Six and Seven Vertebrae in a Ten Year Old Alsatian Bitch

An edematous ten-year old Alsatian bitch was diagnosed of atrioventricular (AV) obstruction on postmortem examination after managing the case for three days before the death of the bitch. The postmortem also revealed a compacted fracture of the last two lumbar vertebrae. The most common causes of atrio-ventricular obstruction in dogs are cardiac tumors. The diagnosis of cardiac neoplasia is usually based on clinical history, physical examination, Urinalysis, radiographic, and echocardiographic methods. Atrioventricular obstruction causes slow conduction throughout the atrioventricular node with variable prognosis ranging from good to sudden death. In this case report, diagnosis was based on Haematology, Urinalysis, Xray, chemical pathology and postmortem findings. The result of cardiac gross pathology revealed a dark red mass attached to the endocardium just proximal to the aortic valve leaflet. Laboratory findings inclusive of the urinalysis were within the normal range..
