Plain-English summary
A 6-year-old neutered male Labrador Retriever was brought to the vet for congestive heart failure, which is when the heart can't pump blood effectively. An ultrasound of the heart showed a large mass near the heart, and after the dog passed away, a thorough examination revealed a significant tumor attached to the heart wall. This tumor was identified as a fibrosarcoma, a type of cancer, and it had spread to the lungs. Unfortunately, due to the advanced nature of the disease, treatment options were limited, and the dog did not survive.

Abstract
A 6-year-old, neutered male Labrador Retriever was diagnosed with congestive heart failure, and an echocardiogram revealed a large mass inside the pericardial sac associated with the left ventricle. At necropsy, the dog had marked ascites, mild hydrothorax, marked hydropericardium, and an 11.0 x 7.0 x 6.0 cm, tan and red, firm, well-demarcated mass attached to the left ventricular free wall. The mass was diagnosed as a fibrosarcoma based on the morphologic appearance and supportive immunohistochemical staining. To our knowledge, this is the first case report of a primary fibrosarcoma involving the left ventricular free wall myocardium, epicardium, and pericardium with a pulmonary metastasis in a dog.
