Abstract

A 3-year-old female Miniature Schnauzer presented with right atrial and right ventricular enlargement. An abnormal blood vessel-like structure connecting to the right atrium was observed on echocardiogram, although a definite diagnosis was not made. Other conditions that could cause right-heart dilation, such as pulmonary hypertension, atrial septal defect, or tricuspid valve regurgitation, were not revealed. Computed tomography angiography (CTA) and cardiac catheterization were performed. An increase in oxygen saturation within the right atrium was observed in an oxymetry run. CTA revealed that pulmonary vein of the right anterior lobe was connected to the right atrium, which resulted in a definitive diagnosis as a partial anomalous pulmonary venous connection.
