Plain-English summary
A young dog was diagnosed with a rare heart condition called a persistent right aortic arch (PRAA), which can cause breathing and swallowing difficulties due to pressure on the esophagus and trachea. In this case, the dog also had a poorly developed left subclavian artery, leading to uneven blood flow in the front legs. Advanced imaging tests were used to evaluate the dog's condition. While the abstract does not specify treatment or outcome, these types of vascular issues often require surgical intervention to relieve the compression and improve the dog's quality of life.

Abstract
Vascular ring anomalies (VRA) are relatively uncommon cardiovascular disorders in canine patients. The most common VRA is a persistent right aortic arch (PRAA) with a left ligamentum arteriosum, however various other vascular anomalies resulting in tracheoesophageal compression have also been reported. We report a case of a dog with a PRAA and left ligamentum arteriosum with a hypoplastic aberrant left subclavian artery resulting in asymmetric cervicobrachial circulation. Selective angiography and ECG-gated multi-detector computed tomography were utilized in the evaluation of these defects. The case presented represents a unique vascular anomaly of the aortic arch not previously described in veterinary medicine.
