Plain-English summary
A 1-year-old female Miniature Dachshund was brought in because a vet noticed a heart murmur during an exam. Tests showed that while the dog had some heart enlargement, it didn't have the typical signs of a common heart condition called patent ductus arteriosus (PDA). Instead, further imaging revealed an unusual connection between a blood vessel and the pulmonary artery. This condition was confirmed as a branch of the bronchoesophageal artery, which is different from PDA. The dog may need surgery to address this issue, but the specific treatment plan would depend on the veterinarian's recommendations.

Abstract
An anomalous shunt between the bronchoesophageal artery and pulmonary artery was diagnosed in a 1-year- old, 3.5 kg female Miniature Dachshund by selective contrast angiography. A cardiac murmur had been observed in the dog during examination at another hospital. The machinery murmur was auscultated at the left side of the base of the heart. Although thoracic radiography revealed mild cardiomegaly, the characteristic findings of patent ductus arteriosus (PDA), including as aortic arch enlargement and pulmonary artery enlargement were not observed. Echocardiography demonstrated shunting of blood flow presumably from the arterial duct at the pulmonary artery carina. Based on the above findings the case was diagnosed as PDA. Angiocardiography was performed to confirm the diagnosis in preparation for surgical treatment, but later we confirmed that the shunt vessel was not PDA, but apparently a branch of the bronchoesophageal artery. The shunt vessel was branching in a complicated manner and shunted to the pulmonary artery.
