Plain-English summary
A dog with a right aortic arch had trouble swallowing due to an abnormal blood vessel (an aberrant left subclavian artery) connected to a persistent ductus arteriosus (PDA), which is a heart condition. Advanced imaging helped the veterinarians see the problem clearly. To fix it, they performed surgery to cut off the PDA, which relieved the pressure on the heart and esophagus. This type of heart issue and its surgical treatment had not been documented in dogs before, but the surgery was successful in resolving the symptoms.

Abstract
An increase in the availability of advanced imaging modalities has led to improved recognition of cardiovascular anomalies. Computed tomography angiography (CTA) provides a non-invasive means of acquiring 3D images with a relatively short acquisition time thereby providing essential information in regards to patient anatomy and procedure planning. The dog in this report had a right aortic arch and abnormal branching with an aberrant left subclavian artery originating from the ampulla of a left patent ductus arteriosus (PDA) that was detected with CTA. The PDA was creating a volume overload to the left side of the heart as well as contributing to the vascular ring and compression of the esophagus. Therefore, ligation and transection instead of a minimally invasive catheter-based procedure was required. This aortic arch anomaly and surgical management have not been previously reported in dogs.
