An 8-year-old spayed Golden Retriever was examined because of recent onset of congestive heart failure complicated by ventricular arrhythmias. Echocardiography revealed a thickened, hypokinetic region of the left ventricular free wall. Fluoroscopically guided transarterial endomyocardial biopsy of the hypokinetic region of the left ventricle revealed infiltration of the endocradium by neoplastic cells consistent with hemangiosarcoma. The dog's clinical condition deteriorated 7 weeks later, and necropsy confirmed the diagnosis and primary site of origin of the tumor. This report describes the clinical use of an endomyocardial biopsy technique to diagnose an infiltrating myocardial tumor that was associated with signs mimicking canine dilated cardiomyopathy.
