Plain-English summary
An 11-month-old spayed female dog was brought in because she was having trouble exercising and was turning blue when active. Tests showed she had a heart condition called cor triatriatum dexter, which was causing blood flow issues. Initially, a procedure to create a passage in her heart helped, but when her symptoms returned, a stent was placed to keep the passage open. After the stent was put in, her oxygen levels returned to normal, and she was able to exercise without turning blue. This stent placement proved to be a helpful option for her condition.

Abstract
An 11 month old spayed, female dog presented with exercise intolerance and cyanosis upon exertion. Echocardiography revealed an imperforate cor triatriatum dexter with mild tricuspid valve dysplasia, an underfilled right ventricle and significant right to left shunting across a presumptive patent foramen ovale. Balloon dilation of the abnormal atrial membrane was initially successful in creating a communication between the right atrial chambers, but stenosis of the original perforation and persistent clinical signs prompted a second intervention. A balloon expandable biliary stent was placed across the abnormal partition, improving caudal venous return to the right ventricle and reducing the right to left shunt. Three months after stent placement, resting oxygen saturation had normalized. Six months after stent placement, exercise tolerance had improved and exertional cyanosis had resolved. Long term follow up will be necessary to assess for remodeling of the right ventricle with improved venous return. Stent placement can be considered as a palliative treatment option for cor triatriatum dexter, especially for stenosis post-balloon dilation.
