An 8-week-old, female intact, Staffordshire Bull Terrier presented to Cornell’s Cardiology Service in March of 2015 as a referral for a continuous heart murmur. An echocardiogram and computed tomography angiogram (CTA) with contrast were performed, revealing a large diameter PDA, a vascular ring anomaly due to a persistent right aortic arch, severe pulmonic stenosis, a persistent left cranial vena cava, and an aberrant left subclavian artery originating from the PDA. It was decided that immediate treatment of the PDA and vascular ring anomaly was necessary, and a 3D printout of the patient’s heart was produced prior to surgery to aid in surgical planning and instrument selection. Surgical correction was successful, and the patient was discharged with instructions to return for suggested treatment of her pulmonic stenosis. This report will discuss the presenting complaint, diagnosis, and treatment for a dog with a patent ductus arteriosus and a concurrent vascular ring anomaly.
