Plain-English summary
A 3-year-old German Shepherd was brought in because he was having trouble exercising. The vet found he had a patent ductus arteriosus (PDA), a heart condition where a blood vessel doesn't close properly. After trying two different methods to fix it without success, the vet placed a special covered stent in the dog's aorta, which successfully closed the PDA. Eight months later, the dog was doing well with no signs of the condition and no issues found on follow-up tests.

Abstract
Patent ductus arteriosus (PDA) with unusual morphology was diagnosed in a 3-year-old German shepherd presented for exercise intolerance. Two interventional PDA closure procedures with various Amplatzer devices and one surgical ligation were attempted to close the PDA. However, PDA closure failed with both methods due to the unusual morphology and the severe enlarged ductus ampulla. Therefore, the patient underwent an aortic covered stent placement, and successful closure of the PDA was achieved. Eight months after the procedure, the dog was free of clinical signs and no residual flow was identified through the PDA on transthoracic echocardiography. Moreover, computed tomography angiography demonstrated correct stent positioning, with no evidence of thrombus formation, damage to the stent, nor any aortic wall abnormalities. Aortic covered stent placement is a viable option in dogs with unusual PDA morphology.
