Plain-English summary
A 5-year-old male mixed-breed dog was brought in for a heart murmur but showed no other symptoms. Tests like echocardiography and CT scans revealed a rare condition where the left pulmonary artery was completely interrupted and the right pulmonary artery was narrowed. Fortunately, the dog had developed alternative blood vessels to supply the left lung. While this condition is uncommon, the dog was stable and did not require immediate treatment.

Abstract
This case report describes a rare disorder of a left pulmonary artery interruption with concurrent coarctation of the right pulmonary artery in a dog. A 5-year-old, male neutered, mixed-breed dog presented for evaluation of an asymptomatic heart murmur. Echocardiography and computed tomography revealed complete interruption of the proximal left pulmonary artery and coarctation of the right pulmonary artery. Collateral circulation to the left lung field was provided by a dilated bronchoesophageal artery with evidence of left pulmonary hypoplasia. Pulmonary artery interruption and coarctation is rarely reported in the veterinary literature.
