Plain-English summary
A 5-year-old miniature dachshund was brought in because he was showing signs of congestive heart failure, including fluid buildup in his abdomen. An ultrasound of his heart revealed a tumor on the tricuspid valve. The veterinarians performed open-heart surgery to remove the tumor, which was confirmed to be a myxoma (a type of heart tumor). After the surgery, the dog's fluid buildup went away, and he showed no further signs of heart failure. He remained healthy and stable for over two years following the procedure.

Abstract
A 5-year-old, 7.6-kg male miniature dachshund presented with right-sided congestive heart failure and ascites. Echocardiography revealed a tricuspid valve tumor. Open-heart surgery with cardiopulmonary bypass was performed via right atriotomy and the tumor was excised from the septal leaflet of the tricuspid valve. Histopathological findings confirmed the diagnosis of a myxoma. Postoperatively, the ascites resolved and no signs of right-sided congestive heart failure were observed. The dog remained clinically stable for 727 days after surgery. This conclusion reinforces the novelty of this report, as successful resection of a tricuspid valve myxoma has not been reported in the veterinary literature.
