A 6-month-old female Golden Retriever was presented to Azabu University Animal Hospital for evaluation of a congenital heart disease. Findings fo the right ventricle, which was divided into two chambers by abnormal muscle bands, were detected by two-dimensional and pulsed Doppler echocardiographic examinations. Furthermore, measurement of blood pressure by cardiac catheterization demonstrated a 5.5 mmHg pressure gradient between the two chambers in the right ventricle.<BR>At three and six months after the initial examinations, this disease was re-evaluated. In pulsed Doppler echocardiography, blood velocity in the right ventricular outflow tract tended to increase, and progression of the obstruction in the right ventricle was suggested.<BR>These findings suggested that the cardiac pathophysiology of this case was progressive cardiac disease.
