Study design: Case Report
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.
