Abstract/OtherAbstract:
A 5 mo old female rottweiler was referred for evaluation of a suspected congenital heart disease. Clinical signs included anorexia, exercise intolerance, and severe loss of body condition. Clinical examination revealed dyspnea, pale mucous membranes, and weak femoral pulses. Pleural and abdominal effusions and iron deficiency anemia were identified. A distended intrathoracic caudal vena cava (CVC) visible on thoracic radiographs suggested that the modified transudate abdominal effusion was the result of improper venous return to the right side of the heart. Cor triatriatum dexter (CTD) was diagnosed via echocardiography but did not explain all the anomalies detected during a contrast echocardiography. Abnormal communications between the CVC and azygos vein and the CVC and thoracic duct were subsequently identified by abdominal ultrasonography and angiography. Medical management with diuretics, iron supplements, and surgical treatment of CTD resulted in normalization of the respiratory rate, the exercise intolerance, and the anemia. To the authors' knowledge, this is the first reported case of CTD associated with shunts between the CTV and both the azygos vein and thoracic duct in dogs. This report emphasizes the importance of presurgical assessment of concurrent thoracic and abdominal congenital vascular abnormalities.
