Abstract
A 6-month old Labrador retriever was presented with an acute history of collapse during exercise. A grade III/VI left basilar systolic murmur and thoracic radiographs showing severe right heart enlargement with an enlarged main pulmonary artery were most consistent with a clinical diagnosis of pulmonic stenosis. Echocardiography revealed an intracardiac mass partially obstructing the right ventricular outflow tract. The mass was surgically excised, and histopathology diagnosed a benign vascular hamartoma of the right ventricle. Short-term follow-up showed resolution of clinical signs with no evidence of local recurrence. Intracardiac masses should be considered a differential diagnosis for patients with acute-onset syncope.
