A 4-years-old, intact male Golden retriever dog was presented with abdominal distension and dyspnea. Physical examination revealed arrhythmia and cardiac murmur. Generalized cardiomegaly, pleural effusion and asciteswere shown on thoracic and abdominal radiographs. Two-dimensional echocardiography revealed abnormal mitral andtricuspid valve motion, mitral and tricuspid regurgitation, left ventricular eccentric hypertrophy and left atrial dilation. Color-flow Doppler imaging revealed turbulent flow extending into the left ventricle during diastole from the mitralvalve orifice, and into the left atrium during systole. Spectral Doppler recordings revealed highly increased early diastolicmitral valve inflow and prolonged pressure half-time of mitral inflow. Based on the echocardiographic examination,the diagnosis was made as the mitral valve dysplasia concurrent with mitral valve stenosis and tricuspid valve dysplasia.
