Fallot's tetralogy in a European beaver (Castor fiber).

摘要: Abstract A 20-mo-old, female, 9-kg European beaver (Castor fiber) presented with apathy, reduced appetite of 3-day duration and a grade 5/6 systolic heart murmur. Thoracic radiographs revealed diffuse broncho-interstitial pattern suspicious for bronchopneumonia. The echocardiographic findings hypertrophied right ventricle, ventricular septal defect overriding aorta, infundibular pulmonic stenosis were consistent Fallot's tetralogy. Even though the bronchopneumonia rather than congenital cardiac was considered primary importance presenting clinical signs, latter relevant decision not to continue any medical treatment. Both disease processes confirmed on necropsy.
