Plain-English summary
A 4-year-old Labrador retriever was brought in for heart problems after being diagnosed with fluid in the lungs about a month earlier. An ultrasound of the heart revealed a large mass on a heart valve that was causing severe backflow of blood. Unfortunately, the mass was identified as a type of tumor called a schwannoma, which is rare in dogs. This case highlights a unique instance of a benign tumor in the heart, but the dog did not survive to receive treatment.

Abstract
A 4-year-old castrated labrador retriever presented for cardiac evaluation to determine the etiology of cardiogenic pulmonary edema diagnosed 1 month prior. A large pedunculated mass involving the ventral aspect of the mural mitral valve leaflet and the endocardial surface of the left ventricular free wall, resulting in severe mitral regurgitation, was identified on echocardiogram. Histopathology and immunohistochemistry of this mass and other endocardial masses identified at necropsy for S-100 protein were consistent with a diagnosis of schwannoma. To the authors' knowledge, this is the first case of a benign intracardiac schwannoma described in the left heart of a dog.
