Abstract
Primary and metastatic tumors involving the heart are relatively uncommon in dogs. In this study, we provide the echocardiographic diagnosis of intracardiac masses in 2 Yorksire terrier dogs. In the first case, the mass was attached between ascending aorta and pulmonary artery and caused moderate aortic regurgitation and moderate left ventricular dilation. The case was graded into ISACHC II heart failure. The dog was treated with common cardiac medications (i.e. furosemide, enalapril, pimobendan) and oral chemotherapeutic agent (i.e. lomustine). In the second case, the mass was occupied 2/3 of the left atrium and caused marked dilation of left atrium and severe mitral regurgitation (~5 m/s), but not severe congestive heart failure (ISACHC Ib). Although the nature of progression of the mass was likely to cardiac myxoma, the biopsy was not performed due to the owner's refusal. The dog was currently treated with cardiac medications (i.e. ramipril, clopidogrel) and bronchodilator (i.e. aminophylline). Those two dogs are still survived and are currently regularly checked.
