Plain-English summary
A 3.75-year-old male Chesapeake Bay Retriever was experiencing rapid breathing, difficulty exercising, and a bluish tint to his skin due to a heart condition called tricuspid stenosis, which was causing blood to flow incorrectly. After a thorough examination, the veterinarian performed a balloon dilation procedure to widen the narrowed valve. This treatment successfully lowered the pressure in the heart and improved the dog's overall health, with his symptoms significantly better over the following year. While tricuspid stenosis is rare in dogs, this procedure provided much-needed relief for the dog.

Abstract
A 3.75-year-old castrated male Chesapeake Bay Retriever was referred for evaluation of tachypnea, exercise intolerance, and cyanosis. Echocardiographically, there was severe tricuspid stenosis and right-to-left atrial-level shunting of blood. Marked compensatory polycythemia had developed; the PCV was 75%. Balloon dilation of the tricuspid stenosis was performed. Subsequent echocardiographic examinations demonstrated a reduction in the pressure gradient across the tricuspid valve. The PCV returned to the reference range, and the dog's clinical status improved during the 12 months after the procedure. Tricuspid stenosis is an uncommon lesion in dogs and, in the dog of this report, was assumed to have resulted from tricuspid dysplasia. Cyanosis was a result of right-to-left shunting of blood. Limited treatment is available for dogs with cyanotic heart disease. In this dog, balloon dilation of the stenotic tricuspid valve was palliative.
