Plain-English summary
A 6.5-year-old male Border Collie was having trouble exercising and showed signs of cyanosis (a bluish tint to the skin) while working at high altitude. After tests confirmed a small hole in the heart called an atrial septal defect, the veterinarian used a special device to close it. This procedure helped the dog, and afterward, the owner noticed that the dog no longer had issues with exercise intolerance or cyanosis. The dog was able to continue its active lifestyle without any problems.

Abstract
A 6.5-year-old male Border Collie presented for transcatheter closure of an atrial septal defect due to exercise intolerance and cyanosis while working and training at altitude. A small, left-to-right shunting secundum atrial septal defect was confirmed with no evidence of significant right-sided volume overload. Pulmonary hypertension with subsequent right-to-left interatrial shunting occurring during exercise at high altitude was suspected and prompted the closure of the defect due to the dog's continued athletic requirements. The anatomy of the defect prompted use of a patent foramen ovale occluder rather than an atrial septal defect occluder, which was deployed using a combination of fluoroscopic and transesophageal echocardiographic guidance. The owner did not report continued exercise intolerance or cyanosis and the dog's lifestyle and residence at altitude was unchanged.
