    Background: Myxoma is a very rare benign cardiac tumor in dogs. This is the first description of a cardiac myxoma
    originating from the left ventricular outflow tract, presumably causing sudden death.

    Case presentation: A previously healthy 12-year-old male West Highland white terrier was found dead during its
    1-week stay in a kennel. The dog was known to have a cardiac murmur. On necropsy, a pedunculated neoplasia
    was found attached to the interventricular aspect of the left ventricular outflow tract, resulting in almost complete
    obstruction of the aorta. As this was the only abnormality identified, the tumor was considered as the cause of sudden
    death. Histopathologic findings were compatible with a myxoma.

    Conclusions: Benign intraluminal tumors of the heart are very rare in dogs, but may have fatal consequences. Echocardiography
    could have revealed the cause of the cardiac murmur of this previously asymptomatic dog. Surgical
    removal could have been possible, as the tumor was pedunculated.
