Plain-English summary
A young dog and an adult dog were brought in with fluid buildup in their bellies, while another young dog was struggling to exercise. Tests showed a heart condition called cor triatriatum dexter, where a partition in the right atrium was causing problems with blood flow. The vets used a balloon to widen a small defect in the heart's membrane, which helped improve the dogs' symptoms. All three dogs showed significant improvement within days and continued to do well over time after the procedure.

Abstract
Two dogs, one immature and one adult, were presented with a history of progressive ascites. In a third, immature dog, increasing exercise intolerance had been noted. Echocardiography demonstrated a partition in the right atrium (cor triatriatum dexter) and echocontrast studies documented normal flow from the cranial vena cava into the right atrium and ventricle. A saphenous vein contrast study demonstrated flow from the caudal vena cava into an accessory right atrial chamber (sinus venarum). The sinus venarum communicated with the true right atrium via a small defect in the atrial membrane in one dog, and additionally with the left atrium via a right-to-left shunting foramen ovale in the other dogs. All defects were visualised on angiographic studies by selective catheterisation of the caudal vena cava via the femoral vein. Balloon dilatation of the defect was then performed using a small followed by a larger balloon angioplasty catheter to enlarge the defect in the atrial membrane. Clinical signs improved within days and were sustained in the long-term in all cases.
