Plain-English summary
A 2-year-old female mixed breed dog was brought to the vet because she had fluid buildup in her abdomen, known as ascites. After some tests, the vet found that there was a blockage in a major vein leading to her heart. Initially, they tried to fix it with a balloon procedure, but the fluid came back quickly. Eventually, they placed a special stent to relieve the blockage, and now, 15 months later, the dog is doing well and hasn't had any more fluid buildup.

Abstract
A 2-year-old intact female mixed breed dog was presented for ascites. Echocardiography demonstrated severe obstruction at the level of the caudal right atrium. Initially, a variant of cor triatriatum dexter was diagnosed, and balloon catheter dilation was performed. However, ascites recurred within a week. Further imaging revealed an obstruction at the entrance of the caudal vena cava into the right atrium rather than a dividing membrane in the right atrium. The diagnosis was revised to suprahepatic obstruction of the caudal vena cava because of remnant Eustachian valve tissue. Deployment of a balloon-expandable biliary stent was performed relieving the obstruction. Fifteen months after stent deployment, the patient is doing well without reaccumulation of ascitic fluid.
